Enemies get stuck either outside or in spawn int he case of super soldiers and can't pathfind to the player. I don't think super soldiers are too fat to squeeze through gaps in the doorways, but their pathfinding needs fixing. I keep finding enemies getting stuck or not wanting to move and when find it it's one random sniper in the courtyard that won't move, and I legit saw a super soldier CAMPING IT'S OWN SPAWN. That's definately a major bug depending on what map you play survival mode on, tbh.
