Yes, I updated the explorer and rebuilt the database.

When many people also had problems with weird balances, the explorer got "disconnected" from the main chain, too. I think my way to do the fix, was not good enough and some wrong blocks found their way into the explorer. That's why some people found a difference between own wallet and explorer. Now everything is perfect again.

Hint:
Balance must always match between your wallet and the explorer. Otherwise one of them is wrong!
If you find some kind of mismatch, please report it, so I can check if it is an error of your wallet or of the explorer.
