[2021] MOVED: Weird glitch, what do i do?

Originally posted by FT: Sometimes this might also be caused by Occlusion ON being glitchy, and turning Occlusion OFF may fix it (but you'll need to turn Occlusion OFF from the MainMenu...can't adjust it while paused in-game).

98% of the time, this is it. It's a known issue with the occlusion system Should be fixed in a future update.
