#What steps will reproduce the problem?

I found this really hard to reproduce. I normally play with characters on Nesingwary and Thrall realms. But yesterday I logged into some old characters on Azuremyst, abandoned over 2 years ago, before I started using UBI at all. Logging in to the same characters today, UBI works just fine.

I had this happen with all of my characters on Azuremyst yesterday, but I've never seen it before, and today I cannot reproduce it. I tried to disable other addons, as well as exiting wow and reloading, but all day yesterday I could reproduce the problem on Azuremyst simply by logging in. Today I cannot recreate it nomatter what I try.

#What is the expected output? What do you see instead?

Immediately after login I noticed that the old mail warnings are missing, and the minimap icon is missing as well. The chat log said UBI was loaded. Swatter gave me an error message (below). After being logged in for a minute or so, the UBI icon shows up on the minimap, the inventory listing for the current character works (both the window and in the tooltips). But the drop down boxes on the inventory window are layered on top of each other and do not respond to mouseclicks. UBI responds to chat commands (remchar and the search feature), but I cannot access the options window at all. Token listing in the inventory window works as well.

#What version of the product are you using?

#Please provide any additional information below.

I tried dumping the WTF data for all of the Azuremyst realm. I checked the .lua data file in WordPad, but couldn't see any difference in the structure between the data for Azuremyst from the other realms. I did not change anything in the file. I always use the remchar and remguild commands to remove data from the UBI datafile.

I forgot to take a screenshot of the corrupted state, sorry.
