My wife is stuck in a wall, can I save her?
Solution 1:
I had this happen with a chicken once. Near the end of the game, when you're kicking chickens into a coop, one got stuck inside a wall. Saving and quitting didn't help - the beast was still firmly stuck.
An oddly-aimed kick solved my problem, but that's only because a chicken is an object that you can physically apply force to. You may not be so lucky with your wife. Try Force Push or something similar to give her a nice strong blast out the other side.
If you find that you can't physically move her, then there's not much you can do. After saving, quitting and resetting the game 10 or 20 times, if she's still stuck in the wall... it's likely permanent. Enjoy your new wall-wife.
