I've been having some ongoing issues with heat stroke in v1.3.3. I know how to avoid it, but sometimes it happens anyway around torches. That's fine, that's not the problem.
The problem is that it just doesn't go away no matter what I do. I've emptied my inventory, including armour and moved away from torches, lava and furnaces, my whole base.
But the game still shows my temperature gradually increasing, even though I know the whole biome is "frozen ocean".
The only fix I've found is logging out and logging back in again. Is this a bug, or is this just how heat stroke is supposed to work? If it's the latter, what do I do about it?
