I am playing a save in Moonlight Falls. I added a professional bar to the Toadstool so that I can have a mixologist for my sims. I have Register installed, also. The issue is that the mixologist sim doesn't show up at all, whenever I send my sims to visit the bar, the mixologist sim is never there. I have tried everything-- resetting the bar using DebugEnabler, resetting the mixologist sim, removing the mixologist using Register, etc. I've googled this to no end and browsed this forum for help. Can't figure it out! What kind of works is removing the sim, disabling assignment, resetting the bar then reassigning the sim. Then the mixologist sim will show up for maybe an hour or so and work at the bar, but then they'll run home. I've followed them and they literally just go to a random lot and disappear. I know that is what the homeless sims do, though, but I can't figure out why the game is pushing them to leave. This doesn't happen in other saves, and the other register assignments in the world are okay-- potion shop is always staffed, etc. Any help would be appreciated! I have the usual suspects in terms of NRaas mods-- Overwatch, MasterController, Register, SP, etc...I have been using register in my game for ~7 years now and have no clue what is different with it this time!

We recently discussed this topic, so here's what we found:

It seems if the mixologist happens to make a bad drink or two, the game banishes them from the bar for a lengthy time and so they wander off doing something else. You use Retuner to shorten that banishment period, or increase the number of bad drinks they have to make before they get banished.

Good luck!.
