The Ultima Online team posted a couple of updates to the UO website yesterday:

Wanted to let everyone know it is safe for everyone to customize your houses again. We have fixed the existing issue we were seeing.

The team also wants to tell you that we have made a change to the way the In-game codes are accepted and you no longer have to worry about changing the formatting around. You can copy and paste the code in game exactly how you get it from Origin from now on and the game will auto correct it and recognize the code if it is a valid code. If anyone has any issues with claiming codes in game please let us know.

I can’t remember all the details, but I seem to recall that for a while there, there was a bit of a flap over game codes obtained from Origin and whether Ultima Online would accept them or not. I’ll be damned if I can remember all the details, but…evidently this has been resolved.
