My character sprite is stuck on a random bush in the wasteland. My save is far back so I'd really like to figure out how to get free. Can use the other interaction verbs but walking doesn't do anything-- doesn't stutter step or anything. Is there a no-clip I could turn on or something?

You should be able to press CTRL + P to bring up the debug parser. Type .unstuck (including the dot) and press Enter. That should position the character in the right place again, allowing you to walk.
