There needs to be an update or hotfix fast

I found the easiest fix if Sims get stuck after romantic actions (like when they move into a T-shape in a hot tub) is to go into build mode and move the object slightly (sometimes exactly where it was). I do not know if is this is what you are experiencing with woohoo. Regarding the high chair, is your high chair connected to a table, or is it just sitting separate?

I know there are a multitude of bugs that plagued the PC and are now sitting in the console.
