Tried it for several hours today and I finally got 83 armour on Raptor against bot Ozan, but I did NOT get the achievement! All the other achievements I've been able to unlock on bots, so that shouldn't be the problem. But of course in the final battle Ozan struck me to under 75 armour, so is that the problem? If so, then it should be fixed, or the achievement description changed. It just tells you to have 75 armour "in a game", not at the END of a game. Has anyone else experienced this? I don't think many even try to get the achievement since it's been ranked as ultra rare to have unlocked.
