My sims had a keg party a few days ago in game. The party went well, ended with a gold, and I immediately deleted the keg I used during the party and left the reward keg in my household inventory. So there is no keg currently on the lot, just in the household inventory, and that particular keg has never been placed on the lot. Despite this, my sims continue to autonomously queue up, "Keg stand?" with each other.
