Sorry guys, the U2U's were cleaned out by a maintenance procedure, unfortunately the U2U's cannot be pruned they can only be flushed.
The U2U's were never meant to be a storage of important information and the database of U2U's was getting too large.
I can restore the old U2U's from a backup so that you can retrieve any important data that was there, but after 1 week maintenance will have to flush them.
btw, if I do restore from a backup all U2U's from the last 2 days will be lost.
Let me know if you want them restored.
