I've come across only minion glitches one was a biopsy mission and the rooter got stuck in its falling animation so we couldn't get the melee hit on it. that was only once so far. the other one I have happened to me at least twice which is my game crashes sometimes when I'm in a solo incursion and idk why I would be doing so good everything is going right and then boom crash and loose everything. I will say both times were when I was playing eli I think her name is the one with the proximity mines and both times where when i was throwing a stun grenade.
