I hadn't noticed it so much a couple of days ago, but as I'm writing this, things are as you've described.

The wallet page simply hangs up when you go to redeem rewards, and the amounts of STEEM/SP/SBD and USD keep changing, but not to what they should be. I've decided to keep a paper record for the moment.

Of all the Steemit pages I want to be performing correctly always, the wallet page is the one. I'm okay, though, knowing it's hivemind or the appbase changes and not some kind of attack or hack.
