Recommend first reading through the forums for other similar threads, or the bug reports (especially the sticky at the top to see if this is a known issue) before posting yet another thread. Often there are already good ideas posted in these places for what to do.
Also, recommend going into Ur and then coming back to your home. Sometimes that helps to reset things - I had a couple friends where this worked for them, and they didn't have to ask the devs for help - they were able to help themselves. If it doesn't work, file a help case or a bug report rather than posting in the forums. That will get to the devs much quicker and they will be able to help you sooner. Good luck!
