[FIXED] Off Grid Living: Can't clean dirty plumbing

I was able to get my sims to clean a dirty off-the-grid toilet by using the “Tidy up” away interaction on a sim who stayed home whilst I was playing another sim on a different lot. Don’t know if it works for all dirty objects and obviously it only works for households with multiple sims, but perhaps a small workaround for people who don’t want to use a cheat.
