@AlistairAB I don't think I've ever used tech armor (I typically play biotic classes), but I use ammo powers a lot, especially because ME2 drastically reduced the number of powers available for each class/character. When the game last crashed, I was indeed using ammo powers on Shepard and Jacob. I really like the ammo powers though so I don't want to have to stop using them!
Also, there is the possibility that mine crashes even when I'm not using ammo powers, but I'm not sure because I haven't paid much attention to the exact conditions triggering it over the years. But still, even if it's just ammo powers or tech armor that cause the problems, the bug still needs to be fixed because that would make ammo powers and tech armor basically unusable.
