Is it what I should to do to help? As Martin said only last two are usefull...

Happend upon killing last alien in a mission.

[Mattn]

[MikeKle]

I knew there must be a something wrong!
Ok, now I armed and rdy

[MikeKle]

It's also happen upon finishing misison. Might be caused by the fact that an alien killed 50% of his  team with grenade...

[Mattn]

this time it would be interesting to see the game.so location - because it looks like the crash came from there.

./base/game.so(G_EventActorStats+0x3d)[0x26e6e4d]

[MikeKle]

Not like I feel like dumb, I know I am

Do you mean I should run something like
addr2line -e base/game.so 0x26e6e4d ?

##
Do you think I can guess once, what is better to find by some attributes in console output?

addr2line -e base/game.so 0x26e6e4d ?

sorry - i should have mentioned that: yes.
