The update failed message is not part of the _bug_. The FAQ answer that I linked to earlier in our discussion lists all of the known causes for that message. The stats server is functioning properly (I just checked it and refreshed my stats successfully). Try quitting your game and launching it again, which will cause the game to establish a new connection with the server.

The _bug_ does not normally cause stats to "age" off the list (although that does appear to happen in some cases). What we usually see is that the stats suddenly disappear from the list as if they never existed, despite what may or may not be in the database. There may be several bugs involved that are compounding the effects and making it difficult to find and fix.
