Well it seams that i saved my base and in my game there seams to be just 2 Sectoides left, but when i kill those two survivors the game chrash

Is this a known bug? Is there any help exept of reloding an older savegame?

Does the mission end and then it crashes? If not, try searching around the radar room, there should be an alien there.

well.. one camp at the stairs to the radar, while the other one is in the main lift. If i kill the one below the radar, then the last one will come out the evolator... get killed.. and the game crash.

I know I had problems with the game crashing that has something to do with aliens and radars, but I don't know why it happens. It could be that the save game got corrupted though in which case you'll have to find an older save. That's why you should always use multiple saves for missions and have one for the start of the mission which you never save over during the same mission.

ahhh.. i got 3 battle saves and one geo save... i will try an older one

EDIT: Ok it worked... i used an older save and i saved my base

You can add a small level of "stability" to the CE versions by using XComUtil. It "splits" the executable (kind of) and then runs the game via a batch file. If the game "crashes" when entering/leaving combat, often this allows it to keep going as though nothing ever happened.

Mkey... now i eaven manage to destroy an alien base.. but now it chrashes every time i transfer some stuff to my australian base. I can click on transfer and so on, but afterwards, when I click on abourt to return to the base screen it chrash :/

sry 4 doble post.

I avoid the crash by starting the game via dosbox and i could transfer my stuff, sadly i had no sound. Afterwards i can save and reload within xp
