My sim drank the ghost goo and is now stuck as a ghost?!

Sounds likes there's something wrong with the serums... There was someone whose sim drank the smart potion and that sim is now stuck with the temporary genius trait. Judging by it's name, that shouldn't happen, but it did. You can find it in the Get to Work forum under the topic 'trait'. Or maybe it's just a coincidence... It just seems curious to me.

By the way, @blam987 you can reset sims, but I don't know if it works for the kind of issue you have.
