So, I was in the middle of a fight, and I happened to quicksave. I also happened to be midway through the animation of throwing dynamite. I then died. Now whenever I load, my character's stuck part way through the throwing animation, and I can't holster the weapon, open the pip-boy or even pause the game. Is there any way I can fix this without reverting to a save from hours ago?

Oh, and I also can't change weapons or go through doors.

I would recommend saving more often, and not just using quicksaves.

I've had issues with savegame quirks in many games.

I found it's always best to only use quicksaves when nothing is really going on and you're standing still doing nothing. And not near enemies if you're intending to sneak up on them. Sometimes they'll suddenly be aware you are there when you quickload.
