Have you tried putting a door in that opening along the left side. If the corridor leads to an unroofed area without a door somewhere in between, that may be the problem.

I put a door in an that seemed to fix the problem.  I've never had to use a door in that situation before though, any idea why it is suddenly happening now?

Can you reproduce this in a vanilla game? 

If yes, please describe the exact steps and include the log file.

If not, it's mods related and will be moved into Mods Bugs.  We'll still need the steps to reproduce, including your full mod order (or a reproducer set).

I can't seem to reproduce this in a vanilla game.  Sorry about that, I didn't realize there was a separate mod bug forum.

I should preface this by saying that I have heavily modified the game.  That said, during play, my walls just stop supporting roofs.  I can start up a new colony and they work fine, but after a while they just seem to stop supporting any roofs.  If you look in the pictures below the first one shows that the room is  15 blocks wide, so that one collapse is expected.  But in the second picture, AFTER building a wall on the left side, there is a huge collapse which should not have happened.  Those walls are close enough that they should support any roof between them.  I could really use any help in sorting out this bug.  A list of all the mods I have installed are in the second Imgur album.

Ok, guess the forums don't like Imgur too much.  I'll just share a link to my album.

Thank you for the replies.  I think I'll just remove that mod and see if that fixes the walls.

I'm not sure if this is a bug or some kind of conflict with another mod I have but the Reinforced walls don't seem to actually support roofs at all.  Man-made and rock roofs both collapse if you make the room wide enough.  Also, if I restrict a Reinforced Door from being used, Colonists can still go through it.  I have tried redownloading the mod but that doesn't seem to work.  If necessary I can provide a list of the mods I'm running or the xml files themselves.

Roofs collapsing is a standard game mechanic, it happens when the ceiling is unsupported ie. too far away from a wall. To fix this, add small peices of wall periodically to make sure all of the roof is supported. As for the restrict not working, that is something I will look into because I have not noticed this before. I will get back to you when I have a chance to check it out.

I just meant that the bug might be that the Reinforced Walls aren't actually supporting roofs.  I have a mod that tells me the range of support a section of wall gives and when I click on a Reinforced wall it doesn't show anything.

I am having trouble getting the Gentz pack to work.  I put all the mods in the mods folder, then ran the .bat file.  I don't know what CCL is.  When I try to run the game it says the mods are for a different version of the game or corrupted and they get automatically disabled.  Also I read that I should overwrite anything but I'm starting with a fresh install of the game.  Am I supposed to have the old UOP first?
