one of them occurs when I put on the mask, and them a Memory access violation (MAV for short for anyone new) happens. this can happen when the game is loading something, but bug can happen, even when nothing is loading. it just happens at random sometimes. (if theirs already abunch of reports of this bug, sorry for the spam. i'm too lazy to look.

The other bug is that the buildings them self's have no collision and can just walk through, even though some of the buildings look explorable. (again, if this is spam, sorry)
hopefully, you can get this fixed in a future update, soon.
