I have severe problems with customizing my house. Here are several things I noticed in the process:
1) Do not overwrite things like archs and doors. They seem to "linger", so I had at some point doors in an arch. The only way to fix this was delete a thing, then save, then delete, then save, etc.
2) When deleting, UO kept raising the house's value
3) Things one deletes sometimes leave an invisible "ghost". For example I deleted stairs in my garden. I cannot cross the space where they stood, but I can step in the direction of the former stairs.
4) Walls set before suddenly vanished again, leaving open rooms or made death traps out of high balconies.
I don't know if it is a bug of the new client, but I did not exprience these problems before.
Edit:
It seems that, after the daily server save, those "ghost" images have disappeared, I can now access the places as one would expect. Those doors-and-archs-problems were still intact after restart, the solution is mentioned above. House value and wall status are unknown, I was hesitant to touch a now working design
