Dead lock?
So I initially thought I had the father winter problem, but I load my game up and about 2 minutes into playing the game just freezes but the time continues. Only been happening since the Snowy Escape update.
@AshMasters17 The one that's 72 MB is likely affected by the Father Winter issue. 11 MB is a much more reasonable number. So if you don't mind losing some progress, you could revert to the 11 MB save and play forward from there, removing Father Winter as a tradition before Winterfest happens in the first place. Here's how to revert to a previous save:

If you don't want to lose your current save, there are a couple of mods that can help. Descriptions of how to use them are here:
