[A13] Savegame cant be saved anymore

[Perlex]

Hey,
I have a savegame that cant be saved anymore. Everytime I try to save it it tells me that it was saved sucessfully but the savegame is nowhere to be found.
Autosaves also don't work with this save. I transfered the savegame to my laptop and tried to save the game but it didn't work either. I also started a new colony and was able to save it without a problem, so it's definitely the savegame that is somehow broken.

I think it has something to do with a caravan that isn't leaving. I sold them a prisoner that isn't capable of walking and now they just wait outside for the prisoner to come out.
One of them is already dead and the others are just sitting there while starving. I think this is another bug but maybe I'm missing something.

I'll attach the savefiles. The savegame is called "Colwyn".

For anyone else downloading: the relevant World is Kornephoros Zaurak.

I was able to reproduce the issue, and I can verify there are no mods requested by the save.

Steps I took:

• Downloaded files, extracted appropriately
• Loaded colony Colwyn
• Played for a few minutes
• Saved, got the "successfully saved" popup, quit to Main Menu
• Loaded colony Colwyn, and it loaded the colony from step 2 (did not reflect any of my playing it)

I checked the file, and it is not Read Only on my system.  The output log (line 50) indicates saving failed.  Just prior to that is a "Could not resolve reference to object" error.  Output log:

I sold them a prisoner that isn't capable of walking and now they just wait outside for the prisoner to come out.
One of them is already dead and the others are just sitting there while starving. I think this is another bug but maybe I'm missing something.

That's definitely a bug.  A very exploitable bug.  But it shouldn't be the cause of the broken save file itself.

Related bugs:
1. Unreferenceable object (may be the "root" bug)
2. Saving fails, but reports as success
3a. You can sell a prisoner who can't walk and the caravan will simply wait forever & starve, rather than "rescue" or pick up their prisoner
3b. You can capture/rescue incap'd prisoners that have already been sold
3c. Upon recovering, a pawn that was sold and rescued and treated will wander off on their own (not recovered by the caravan they were sold to)

Thanks milon and Perlex. All bugs are fixed.
