I have some issues with XShape as well. I've downloaded the nationality selector mod and the no disappearing corpses mod. I apply them and run XShape (which comes up with no errors and 1 SHA Hash updated just fine), but the game crashes when I start it. The mods are working for other people so I'm a bit lost here. Things I've done so far: - started completely from scratch (i.e. let Steam redownload all corru.. err modified files) - decompressed XComGame.upk (and only XComGame.upk) and moved it to the CookedPCConsole folder - only applied the no decaying corpses mod (i.e. did NOT apply my DefaultGameCore.mod file, nor any other mod) - removed all upk files from the config file but XComGame.upk - ran XShape and got a nice success message - Game crashes immediately at startup Edit: Oh my, after two days of testing I found it out myself just after posting here. The issue was that I left the unpacked xcomgame.upk in the "unpacked" folder that was created by the decompress tool. The game loaded the unmodified .upk but with the exe modified for the modified .upk. That caused the crash. I should read the messages more carefully. I thought the popup was telling me that the XComGame.upk was now internally named xcomgame.upk (small letters), but it actually told me that there were two xcomgame.upk files. *facepalm*
