I found this thermal stone skin has image error(?)
if skinned stone is in inventory or ice box(maybe chest too but not tested) it just shows gray color even if stone's temperature is below 30 degree
that one(skinned only) should be freezing white but it doesn't
so i dropped gray one and the one that should be white is still gray while in cursor
but if dropped on ground it become freezing white as normal.
but picked up and in inventory... become gray and with mod(Show me) you can see its temperature.
should fix the image showing up in inventory and ice box(maybe chest too)
