Routing/Sit down issue on several interactions

I've got one child sim who currently has a loose tooth (like their fifth one, sidenote: very annoying), but everytime I click to 'pull out loose tooth' or 'wiggle loose tooth' they always seem to go to sit on the edge of the pool (which doesn't show up as an action in their queue) and only once in the pool they would remove the tooth. on the fourth time this happened my sim almost froze to death (thank god there's a pleading for revival option). I would really appreciate this be fixed because it is so annoying.
