Twice in less than 15mins I have been knocked by mobs or randomly jumped by the enviroment to invalid map area. First time was the cannon barrel, second time was a rock. In either case, I can't move off it, can't dodge off it, can't use a spell/skill to jump off it. I have to teleport back to town and run all the way back. This map needs some work on collision as its allowing a char to get pushed/moved into invalid places and then locking you there.

Republican Backline - Cannons to the top left, ramp/rock area where you fight two lightning mortar mobs bottom right.
