So, I found this keg-bot in the basemant of an old bar, and after I activated it, I got a new quest with two optional goals - deliver him to a hotel in Goodneighbour, or keep him for myself. I decided "hey, free cold beer - I'm definitely keeping you!", and sent him to Sanctuary Hills, intending to install him as my new barkeep.

Trouble is, he can't be commanded like a normal settler, so I can't actually tell him to tend the bar - he just hangs out next to it like the world's creepiest barfly.

So I thought "well, he's not nearly as useful as I thought - maybe I'll send him to Goodneighbour after all." But that's no longer a dialogue option.

All of which would be fine, and I'd just set the matter aside as one of those wacky Wasteland happenings and go back to ignoring him except when I fancied a nice cold brew - except that the quest is still showing as incomplete, just cluttering up my questlog to no good purpose. Is there some way I can get closure on this quest?
