Currently, when a player has disease.immunity as a permission, this doesn't extend to the temperature system. I'm creating a system where players can sorta choose for themselves if they'd like the additional challenge of diseases, but with this, I can't prevent anyone from also partaking in the temperature system's negative effects. If they get hot enough, they can even still die from being in a hot area for too long, as well as be bothered by negative effects of both ends of the spectrum.
Could you please add a way of turning this off individually, a permission to opt out of the negative effects and messages of the temperature system?
