When testing in creative and switching to survival the player temp does not change with wool armor on or off.

I actually changed the value to 10 to see if that would make a difference and still nothing. I removed all my mods to see if it was something conflicting and that wasn't the problem either.

used temp info and it is working made my assumption on the UI up arrow. Was not sure why i did not see a different when changing the config the first time but all is well!

Turns out i was right at first. Seems to be a conflict PrimalCore. I'll try to find a fix in the config.

Sadly could not fine a config option for it. Left a post on the Primal Core bug page.

im using latest version and it seems to be normal
use the command /tan tempinfo to check it out
sometimes temperature is so cold that even with a full set of wool armor you can get hypothermia

Also in the config files you can change how many temperature each piece of wool armor grants to you
