Dopiaza-I had this problem yesterday as well. I did a reload with the the help of a dev and it fixed it. However, it came back. I haven't logged in yet today to see if a reload again fixed it. I will let you know but in the meantime, you may want to post a bug report and see if they can fix you up.
dopiaza, if you see it again, generating a bug report from the in game dialog might give us some extra information from the session. (It appears you use the debug Flash client, which is great. :)
And I want to confirm again- you just enter your home, and it is like that, right?
(And reloading fixes, similar to the giant trophy case issue you may know about.)
Kevbob-Just a followup for you-this happened again to me earlier today. I reported and contacted you and a reload did fix. Yes this is simply upon entering the house. I live at 1166 Doon if this makes a difference.
kevbob - I think it was actually when I first entered the game - I was in my house from when I quit the game previously. I didn't notice it immediately (I was pottering in the garden at first), but I assume it was like that when I arrived. Re-entering my house in a later session did indeed fix it.
If I see it again, I'll be sure to file a bug report in-game.
