They do like getting stuck on towers now. It's actually very obvious on Crucible:
- Play as the Dark side
- Go to the middle and start fighting the Light demigods, observe retreats.
When they retreat, they go to a little corner between the edge of the path and their tower, but still outside their wall. They just sit there. Eventually they get loose, but then they usually go inside their wall to the other tower, then turn around and go in a straight line past that tower outside of their wall, turn around again and go back in.
This is very common behavior for the Light AIs on that map. Both the corner hiding and the weird path is repeated fairly constantly, so it's a procedural thing.
