Radar in Team Snipers glitch

I just joined a game in progress and had my radar the whole game. Doesn’t really help, other than being able to miss headshots from behind the enemy, but i dont know if this has been reported yet or not. I can post a video of it if need be, but i cant think of any reason why someone would lie about this. Also, it must’ve only been me as none of the enemy would see me sprinting to lifts below them, so i assume its from join in progress.
