[enemies getting stuck on things and spawning in weird places]

I have seen enemies getting stuck on places in the map and spawning in places where they can not move In defense missions. In the defense mission I have been playing the most stephano on Uranus enemies have been spawning on rocks on the walls above the ground and defense point. in the mission I just played belenus in the void, enemies have been getting stuck In a gap between a stair case and pillar beside the stair case. in both missions I have mentioned this has happened almost every round
