You can't reproduce it on a new SP map?

I don't mean fighting. I mean they don't hop in place in your room to prevent its capture.

Load the attached savegame. There is no alternate route. And the weirdest thing is they don't walk on lava if you remove the rampart protecting the bombard.

Are you saying units walking and fighting on lava is intended behaviour?
