So I was exploring my world and I came across this one spot with a small cloud of gas (I don't believe it was radiation, the cloud was very small, no dead stuff around it) which makes the game go completely black when i go near (all GUI wouldn't appear either) with only the sounds playing. I was still able to attack, run commands and open my inventory and pause menu despite being behind a black screen. Playing with 48 other mods, Im not sure whether its a confliction with NTM (I am using HBM NTM 1.0.27 X4480 btw) or a feature, I assume its an NTM thing because of the (small) gas cloud. The black screen goes away when I get killed and manage to respawn (Finding the button is a pain), but when I go back to that spot the same thing happens again, even in creative, so it seems to persist. If its a feature, then is there a way to prevent or remove it ingame? I have been searching all over for an answer.
(And yes, I shared a completely useless screenshot of this)
