After updating the patch all my nick became invalid (although I can see my old stats using the "compare" feature in BFHQ) so I had to start over with a new name. Now an hour after getting promoted to Lance Corporal, I get in-play notification of promotion to full Corporal and my rank in the server line-up shows me as a full Corporal. This has happened twice in the past hour or so. But when I return to BFQC to check on it, I'm still a Lance with a nearly a full bar of progress to go before I'm supposed to make full Corporal. It keeps teasing me with the drum roll and announcement that I've been promoted - which I haven't. I'm mostly pissed I lost my unlocks with the foulup of my original nick though. What's the deal, anyone know?
Log out then log back in. If that doesn't work then log out and back in after like 10 minutes or something it's happened to me before
