Damn, I was hoping they would fix pathfinding in water. I built my base next to a sea and my pals occasionally get stuck in there.. although I built stairs into the sea. Raids are boring as hell as enemies also just get stuck in the water (even though they have these stairs just in front of their noses). Somehow the pathfinding cannot connect swimming in water and climbing the stairs. I've tried various locations and combinations of structures, they never use it :(
