Smoke not shown up for some enemy, 'complain' not working from replay

watched replay after dodgy death from a nub enemy and from his POV there was no smoke visible (I laid down a lot, and so did he). Didnt know if it was an exploit or not so went to report just in case and this option is broken, no complaint form brought up. Tried it from client replay and web replay, both the same.
Thought someone should know. Please dont tell me to post this somewhere else, I wont. Take the info and improve your game or not. Youre welcome.

It’s a bug with smoke, Fire lots more, and don’t rely on it to be active immediately or constantly.

Needs reporting if it hasn’t already (Which it will be on multiple ‘ways’ being shells bouncing and not firing or grens not showing anything)
