enemies getting stuck on things and spawning in weird places

[stailmemes]

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

I have been experiencing the same issue in defence missions and also in others,the enemies would spawn inside a wall where one could damage it or it would get stuck in a random spot.DE please address this issue as quickly as u can because it has made me a lot of missions missing out on rewards and also make me feel unmotivated to play the game.
