Plutonium

As of version r4839 progress doesn't seem to save as well as the previous version.

For reference I played two games in a row without disconnecting. During these games I unlocked a few camos. After game two however I disconnected from the particular server and changed classes and camo's, using the uploadStats command a few times during these changes. Afterwards I joined a server and disconnected after a kill, using the uploadStats one more time in the public match menu before closing the game entirely.

After closing the game and rebooting to check if my progress had saved it resorted back to the point in between the two games I had played. Call it an autosave if you will.

It seems like the uploadStats command is broken in r4839.

Xerxes I currently check around every hour to see if my progress has been saved. Today in around ~2 hours I started Plutonium four times. Every half an hour or so I quit and restart Plutonium to see if my progress has been saved.

Currently going for Diamond SMGs:

Half hour #1: Finished the Skorpion EVO and went for headshots on the Vector K10
Restarting Plutonium to check if my progress had been saved - it did.
Half hour #2: More Vector K10 headshots (at around 58)
Restarting Plutonium to check if my progress had been saved - it did.
Half hour #3: More Vector K10 headshots and challenges
Restarting Plutonium to check if my progress had been saved - it did.
Half hour #4: Vector K10 Gold
Restarting Plutonium to check if my progress had been saved - suddenly I'm back at the progress from half hour #2, it was saved before and now suddenly is gone.

What's going on here?
