[BUG] Graphical Cave Flickering

I've had some graphical bugs on and off and I can't explain how or why. All I know is that I've been going back and forth between a desert and an arctic biome via a cave and I've been moving somethings and suddenly I started having some graphical flickering effect of being in a cave. I'd even get the cave debuff for a split moment and it's all super quick, but it's sporadic and inexplicable as to what I did to trigger it. I've quitted out of the game and have loaded back in and everything is fine so far, but can this be looked into?
