So usually everything is fine when I first start playing, everything is clear but if I decide to switch my character multiple times I have to restart my game because these weird blotches appear on characters that are usually black, but they clear away if my camera gets close enough. Same with the map, there will be huge black blotches on the ground but if I run up to it it just moves ahead. This only happens if I keep changing my char's or I play without restarting my game often. Why is this?
