In reading your response to Zoe's thread, I did have the foresight to try and do something as you mentioned the moment it was occurring this AM and unless there is another way....
My example in my original post since I took it's rantings out, was I was wearing a pair of prim shoes. I changed into another pair of prim shoes. Didn't strike my fancy for the day so I decided to switch back, and that's when it happened. Not the only time it's happened over the past few days (objects and images included), but just my most recent example as of this AM.
When I was starting to have the problems of things giving me the messages, I immediately went to right click on the item in my inventory to try and recover a UUID (via the copy UUID selection). But low and behold it's darkened out and not available.
So how do we keep track of UUID's on items that have suffered from this problem for you to possibly hunt down if it won't allow us to see it from our inventory?
EDIT: Yes the shoes I speak of for example are shoes I created and I have full permissions. As for the hour bit as of this AM, I don't know because I wasn't in maybe an hour before update time came around.
