ok, so my player, after i loaded a save, froze in place and fell over and would not get back up. What can i do to prevent this?

Are you able to load another save point?

If so does the problem keep happening?

If so, does your guy spawn on the ground or do you have a few moments before he falls in a heap?

If you have a few moments try fast travelling, it may stablize him. If not then you may need to restart your game, or wait for something to attack you, try going into VATS and firing at something?

Hope atleast on of these helped somewhat.
