i found some troble like in cave deep down it freezing or hot deppen on the biom weather normaly cave will insulate like stable at 25 c can u solve it ?

This is definitely strange. Cold Sweat does have a new system of calculating this in the most recent versions, but I haven't had any problems with it so far. Can you run /temp debug @s world and take a screenshot? This will give me some more information on how your temperature is being affected and where it might be going wrong.

like this one ?

Yes, that's it. I did some more testing and was finally able to recreate the issue. Turns out it's because the "insulation" underground simply isn't applying because it doesn't think the player is in a valid dimension. This was a pretty easy fix.

oh okay that good to hear that and thank for attention and ur work i wait till it next update
