I had actually noticed this since the game came out but thought it would be addressed. Just saw it again today. For those who don't know, when an Assault spawns a Buzzer on Steel Peel, the Buzzers get caught on the OUTSIDE wall of the play field making them effectively useless. They will just hang there, one or two might be able to slide down and towards the enemies, but otherwise they just keep slowly sliding away from the arena. This is especially annoying because Steel Peel attracts a lot of Snipers and Buzzer's are quite effective. Is it just me? Or do others know what I am rambling on about?
I don't think it happens every time, just occasionally. It's a known glitch that can happen in any level, where buzzers will fly straight up to a wall and just get stuck.
We know there are weird issues with flying bots pathing around walls, unfortunately there's not much we can do about it without rewriting the system. We may address it down the road.
The best time to spawn buzzers on steel peel is when enemies are camping your jump pad bridge. They go right inside and attack those people. Sadly randoms won't ever use buzzers in this fashion when their bridge is being camped.
