You need to fix the weapons_gc.xml file : search and replace "<Set3 ap="15" accuracy="130" />" by "<Set1 ap="15" accuracy="130" />". I'm experiencing game crash in some ground combat battle enemies turn depending of the enemies. It happens with systematically with adrons elite and another unidentified enemy (perhaps a specific orb color, but not sure). The only way for me to get thru this bug is to restard in debug mod and kill those crashing enemy. This solution could fix the problem another poster had listed above (kind of late since it was more than one years ago).
