Bots stuck they cannot jump down. I jumped next to them and wanted to reach the tome, but fell. The bots followed very slowly after a lot of time one by one while I climbed the cabinets. They fought one or two waves of hordes up there.
Bot stuck at climbing ropes. Later the bot somehow fell under the map and died. I saw the outline falling.
I was there when the bot died.
Bots stuck at a painting entrance, but I went there from the other, cannon side.
