i now double checked it, gave each individual the ammo next to the gun just not to make any mistakes, and on the next mission same problem. now i am on a terror mission and i cant get past the alien tank because i lack the ammo. and i really dont want to ditch these guns just because of a bug. well guess ill wait a couple more months until the game becomes a bit more stable... still a long time until xenonauts 2 comes out anyways XD
