hitting enemies into walls

so, apparently you can keep hitting enemies back until they hit the wall. Then you can hit them INTO the wall, where they will sit like lifeless dolls...

Also, apparently if you keep pushing Brutus back with ice wall or something, he can actually go into the terrain and when he dies, his loots are dropped in the terrain and you cant get pick it up

I think the bug is the fact that the enemies can be hit into walls, unless this was intended then I'm sorry i posted.
