All traps (Trapper/Hag/etc) are currently bugged

Toothbrush

Traps cannot currently be placed within a good few meters of the gates. The current patch notes mention a bug fix in which there were problems previously in what I believe was the building on Ormond, but there are several maps in which there are large patches of ground that you cannot place traps anywhere on. I noticed this especially on Autohaven since it was the most recent map I played.

I have not played the other killers as much, but I know the Trapper has been having issues like the image I included. Traps are spawning within objects and walls so they become unusable and hinder the killer.
