The ghost hunter profession was broken by a recent patch and fixed with 1.50. However, ghost hunters who were employed prior to the patch still have issues. The only way to fix that is by quitting and rejoining the profession, which sucks, but it's better than staying in a glitched job.
Stuck horses are common. An easier way to free them is to open up the cheats panel and reset the horses out of there.
I once had a nudist sim. Once I changed him into his everyday clothes, he cut it out. The fix to that is usually to manually change them into a better outfit and go to the dresser to remove extraneous career outfits (or so I think).
