My sim is stuck in a loop

My sim died and I wasn't that stocked, so I tried to revive it with the Ambrosia meal. There was a problem with that, the sim constantly ignored other tasks and kept trying to "react to becoming a ghost". Anything I told it to do was immediately forgotten, and even their needs suffered because of it. No matter if it was me, or the game trying to make it sleep, eat, or do anything, the action was overthrown by "reacting to becoming a ghost". Even after making them human (Only because of another household sim), they still did not stop "reacting to becoming a ghost". I don't know what to do. I've tried resetting the sim in multiple other ways, and I really don't want to kill them again.
