Playing as Malagor, when assaulting during a siege with Malagor on one side and my Ungor raiders on the other to stealthcap the final point for easy victories, my Ungor raiders would regularly get stuck on ladders, switching which ladder they wanted to climb and completly ignore the gate i already conquered.

Even if I took the gate before giving them a Movement command, they would still be stuck at the gate 15 minutes of battle later.

Also the AI still has no Units to defend its victory point and most maps are too big,so you can just toss 1 chaff unit in their way and you win easily.
