Ah, the tales of the runaway butler. I was quite unpleased when I discovered my butler not only dissapeared, but continued to demand payment. I mean, not that I was necessarily peeved by the money loss, being a distinguished director receiving jacuzzis left and right (what do they expect me to do with a seventh hot tub?!), but it was none the less grating.
I eventually devised a plan to shrink my funds under 1k and keep them their so he'd be furious from not receiving payment. At which point I just... stopped receiving word. No confirmation that he was quitting do to wages, just silence. It was really weird.
Another time, a butler's service somehow transferred from one family to another when I changed households.
