Happened again tonight. Seems to be directly related to multiplayer games - turf warfare.
Played 4 matches tonight, leveled 3 different characters both zombie and plants to level 10. Switched characters after max 10th level figured I would promote when I got back to the backyard.
Got back to the backyard, looked at my gold, stars and quests that I had completed during the 4 matches. I had half of the ones I did -back in my quest log with "some" progress on them. I lost the coins and stars of course that was associated with them appearing back in my quest log.
Went to promote my 4 characters who got to level 10. And what do you know all back to level 7 , 8 that I was before playing those multiplayer matches.

I have hundreds of hours into the game, and until last week this wasn't happening. I don't know if it was linked to the patch I don't know if it appeared immediately following that release.
I already flushed my DNS, ran a tracert (ultima online tracert to ea servers 100 tests) and gave it into the technical support
It really appears that the game isn't syncing or saving cloud data. Or if it is, its occasionally not committing data to the database, or doing some sort of rollback on the failure of the write. I don't know how it works behind the scenes that's just what it appears to me looking at the black box.
