I recently experienced this bug while playing a match, I’m not quire sure how to report it here without giving it away and risking other people exploiting it till it’s fixed.
But basically a player was able to place the turret in a certain spot where it was able to shoot through a wall but it couldn’t be hit through the wall.
Any bugs you want to give us without giving away exploits you can create a support ticket. 
It’s too late everyone already knows about it now. I was just in a match where 3 guys where placing them and they were shooting through walls. It’s on underground map on the roof of the room where you destroy fan (first objective).
Yeah I sent in a ticket and such…but I guess more people discovered and are using it now…least the new rotation will be up soon.
What it’s insane is today, ALL SERVERS i joined, all voted for Underground >_< I had to join in midgame to evade that map
