I don't see a bug here personally. There is a difference between a tile that is hard to reach, and one that is unreachable. Both the tiles in the screenshot are simply hard to reach, and require the Pawns to walk over the Hydroponics Basin (at a greatly reduced speed) in order to reach them. But the same applies to most of the objects in the game, and Pawns will walk over Solar Generators, Workbenches, Turrets etc in the same fashion. There are some objects they can't walk over, such as the Nutrient Paste Dispenser and Geothermal Generators (and likely a handful of other things), but these are in the minority right now.

So this is more a matter of planning and base design. If your Pawns are walking over your Hydroponics instead of going around them during regular movement, then that would be a pathfinding bug. But walking over them because it is the only way for them to reach a sowing area, that is WAD in my book.

This topic has been moved to Mod bugs.

Thank you for the log file. Much appreciated. This certainly looks like a mod problem (so I'm moving this thread to mod bugs now).

I'm not the best at reading log files unfortunately, but as far as I can tell there seems to be problems with the More Factions mod, and probably Hospitality as well. Plus the screenshots you and MerlosTheMad posted seems to indicate another set of issues going on as well (possibly to do with the mods that haven't been updated to A15 yet. Although that's just an educated guess on my part).

Not sure if anything can be done about this at the moment though, as it might just be a case of either waiting until all the mods being used are updated to A15, or going into troubleshooting mode and enabling each mod one by one until the mod (or mods) causing the problem is identified (or of course someone with better log reading skills than me might be able to identify the exact problem from the log file and/or screenshots).

Either way, @ Maxim+MerlosTheMad - thanks for posting about this problem, and for providing answers, screenshots and logs etc.

It seems the erosion is spreading!

@ Maxim -

1 - Are you running the latest version (A15b)?
2 - Are you using  any mods? If yes then goto 2a+2b.
2a - If yes to the above, have ALL these mods been updated to run with A15?
2b - Do you get this problem when playing vanilla?
3 - Do you get this problem when starting new colonies, or only when loading a saved game?
4 - Are you able to attach the "output_log.txt" file to a post? (see my earlier post for details of where to find this https://ludeon.com/forums/index.php?topic=25161.msg257291#msg257291)

EDIT: I see Tynan is already on this.

That's because Tynan's had his Go-juice this morning! Try some today and never be ninja'd again!!!

This bug should have been fixed for A15

Is anyone still experiencing this issue in A15? And if so can they please post a scenario file showcasing this issue, or reproduction steps. Thank you.

Edit - 10th September -
A user responded to my post with confirmation that this bug, or more likely a variant of it, was still present in A15c (0.15.1284). So I split that post to create a new bug thread, and will close this thread as a result. Here is a link to the new thread.

I should have a save game available where visitors are eating my (forbidden) survival meals. These particular visitors didn't bring any food with them though. One of these two things, either eating the player's food, or the visitors not bringing their own, seems like a bug to me.

Edit - Here are a pair of before and after saves.
https://dl.dropboxusercontent.com/u/97382000/Visitor%20Eats%20Player%27s%20Food.rar

If you load the before save, then as soon as one of the visitors crosses the white (planning) line, they become aware of the survival meals and make a beeline for them. In the after save, a Visitor named "Key" can be seen doing just that. The visitors will still go for the meals even if the doors are forbidden.

No worries, just glad to hear the game is running properly for you again. Still find it a bit odd though that the mountains appeared fine to start with and only messed up when you loaded a save game?! A mystery I guess.

As jayerbayer says, can you please confirm whether you are using any mods or not? Since that seems to be the most likely cause.

(and I've moved this thread to mod bugs for now)

Thank you for taking the time to answer the Q&A. The follow-up Q's are...

4 - Thanks for the screenshot of the in-game debug log. It certainly looks like there are a number of issues going on there. What is really needed though is for you to attach the "output_log.txt" file to a post. Details of where to find that can be found in this post.
https://ludeon.com/forums/index.php?topic=513.0

Although if you're using windows you should be able to just right-click the desktop icon>open file location, and the RimWorldXXXXWin_Data folder should be in front of you (XXXX denotes the version number, which should be 1280 for v15b or 1279 for v15). The "output_log.txt" file should be in that folder.

6 - Do you still have this problem if you disable all the mods and just run vanilla?

If not then that pretty much indicates this is a mod problem, possibly with the Wort as you mentioned. In which case, and assuming all the mods are A15 compatible, then the troubleshooting process involves disabling (or enabling, whichever your poison) each mod one by one until the one causing this problem is found (and then reporting it to the mod author). Unless the log file is specific regarding which mod is causing the error.

No problem. And thanks for posting again to confirm a non-bug. Much appreciated,

I'll close this thread now.

Erosion maybe? Or...

1 - Has your computer done any sort of automatic update of video drivers recently?
2 - Does this problem exist when starting a new map?...
2a - ...or is it only affecting that particular autosave? (if only this one save game, then can you please post this save file?)
3 - Are all the different mountain types affected, or is it only one type in particular? (the mountains in the screenshot appear to all be of one type, but that might just be part of the glitch).
4 - Does the log while show any errors? And if it possible for you to please attach the log file?
5 - What O/S are you using?
6 - What version of RimWorld are you running, and are you using any mods?

I think that covers most of the obvious troubleshooting questions. I've also moved this thread to Support since at the moment this seems more likely to be a video driver O/S error than something to do with the code.

Mine a 18x14 room inside a mountain.
Guarantee it has a thick roof.

After you mine it, everything ok.

Build a wall around the room, making a 17x13 space.

Then start to unninstal the walls, the roof will fall.

Can I please ask if you are sure that the above is the exact order you did things in the diagram you posted in the OP? At no point did you build some wall sections before the mining was finished? Because if you try to dig out a 14x14 mountain room then the roof will collapse. Here is a diagram and save games to illustrate this. (save games are v.0.15.1279).

https://dl.dropboxusercontent.com/u/97382000/Mountain%20Roof%20Test.rar

In the "Before" save game I have dug out a 12x14 room. There is no roof collapse because it is within the maximum roof support distance (6 tiles from support, so 12 tiles wide in total). I have also ordered the room to be mined out be 14x14.

At some point during this process the roof will collapse, and between 1-4 sections (depending on the order the tiles were mined) of "Collapsed rocks" will appear in the centre of the room. You can mine these collapsed rocks until there is only 1 left, but once you mine that section then 4 new sections will appear because these collapsed sections were acting as the roof support and so the roof will collapse again once the last support section is mined. This is demonstrated in the "After" save game.


If you still think there is a problem here then can you please post a save game file(s) demonstrating it, because the steps you provided lead to the roof collapsing while trying to dig out the 14x18 room (or 14x14 in my example).

Hi, thank you for purchasing RimWorld, and welcome to the forums.

Have you tried doing a complete uninstall & reinstall on your desktop? I'm far from an expert at reading the log file, but it seems the game is having trouble ether accessing or finding a bunch of RimWorld files. And if you have just installed it on your desktop, then a corrupted installation sounds like a possibility.

If the above doesn't work, then please post again and I'll locate one of the mods* with log file reading skills to assist you further (*if they don't notice your post in the meantime).

Can I please ask where the potatoes are in relation to the meat and vegetable stockpiles (which I presume are on the stools)? A full screenshot of the setup might be useful.
