This isn't a problem but just a funny story...
I kept noticing that these weird water puddles kept appearing in the kitchen near the bar and Bonehilda's closet. Bonehilda always mopped them up, but I couldn't help but wonder where they were coming from. So, I decided to watch the kitchen for a sim day and see if I could spot the culprit.
As it turns out, my Bonehilda has developed a drinking problem. She makes herself a drink (or two or three...) at the bar and drinks it. But being a skeleton with no stomach, the drink just ends up as a puddle in the floor. Then Bonehilda laughs and claps her hands like it's the funniest dang thing she's ever seen, then mops up the mess.
