I played breach against bots and at some point the ram was standing still, but our(defender) pikemen started going to the far away enemy pikemen and completely ignored the ram.
The ram wasn't close enough to the gate to use the cauldron, so unless it would advance further there was no way of ending the game.
It's the second time I had this problem. First time was a few months back. Same map (don't now the name, but it's the viking castle) and roughly the same place of the ram.
I do have screenshots of both times
