Well, the stairs are broken. At the connection point of 2 objects the avatar now stucks. It worked before the update, nothing in the room was changed. Thea avatar runs on spot, nothing was changed in the room. I think this is a serious critical or even fatal buck: Many user rooms are not usable anymore.
I'll quote lyrics from a song that strongly applies to most people in the "What good is a key, if you can't see the cage"
Also loved that Rowdy Rowdy Piper movie
