I'm having a problem that's making my game unplayable...

I'm doing the quest "The Lost Tommies," and when I have to escape the Bunker, I'm dying instantly when hit by the fire, even though my health is full.

Is there a way around this?

I tried getting support on Folon's Cabal Discord, but they repeatedly just say: "We don't support third-party mods (ironically, they themselves are a third-party mod)," and they don't answer anything or offer any valid help.
