I found a bug where the game don't save screenshots.
I'm using a modified shortcut to change the Save Data folder like explained here (https://www.reddit.com/r/RimWorld/comments/39l5kg/changing_save_location_in_a11/cs4busc) or here (https://ludeon.com/forums/index.php?topic=16341.msg176061#msg176061). I'm using the "-savedatafolder SaveData" method. This works all fine for the saves, worlds and configs, but if make a screenshot the game wont save it and show this "Failed to store screen shot" the outputlog.txt (is attached).
I found also that if shortcut is modified like this '-savedatafolder "D:\Games\RimWorld\RimWorld914Win\SaveData"' screenshots will be saved properly.

I'm guessing that "-savedatafolder SaveData" causes the screenshots directory to get an invalid path/handle. Good to know that a full path works, but that ruins its portability.
Did the screenshot folder already exist when you used "-savedatafolder SaveData"? Did you try using a current-path variable (%CD% on Windows)? Does anyone know if screenshots can have its own commandline argument?
i thought this was reported as a unity bug or something, im sure Tynan is aware of this one.
