Character fainting as soon as I load.

[Misteezy]

I tried going forward in time by one day, and now my character won't stop fainting when I load in and won't let me play my save.

This usually means you are loading in on an invalid spot like on top of a building or similar structure. Can you provide any more details? It may also be worth to look at it in a save editor.
