Glitched-up LIVAN saves

Okay, first post here and it's not a happy one. I'm a massive fan of LIVAN (except for those mustard gas grenades... they detonate REALLY easily), but for some reason, several autosave files and many brave growers have been lost to spontaneous crashes. The files are attached here... I forget the exact circumstances, unfortunately, but one was in the vicinity of a zombie when his next step brought the crash. Another was attempting to chat with a light frog for INT training. All four crashes were the generic "LIVAN has stopped working" errors by Failure Vista. Can someone check these for abnormalities?
