Igor's Drawbridge battle, I use a bomb to blast the enemies bridge, but of course I had made my own bridge just off to the right side. The enemy starts pursuing Emma on my bridge but no humans are in range. Since I made the bridge, they decide to start breaking it, ensuring that I'll be able to make a clean getaway. Not exactly a bug, but an edge case where the AI destroying player made objects is not something that a player would do and counteracts their primary mission of Killing Emma or Sabina
