No blue skin for freezing sims

[Dizzymental]

This mod may already be out there but I'll be stuffed if I can find it. Searched for hours on google and all I'm getting is the no blue skin vampire mod. I'm looking for a mod that stops the sims changing into blue skin when they start freezing. On my crappy machine there is an annoyingly long delay while it freaks out over giving the cold sim a blue tint.
