There is a bug in balance computation.

Applies to few rare addresses, now I have found 3:

https://emercoin.mintr.org/address/EUgUWBzzgQQdvxD94ruyHiLDRkdK31MnEZ
https://emercoin.mintr.org/address/EKTAzV8WY5sEafTFsb6HV68LJ5TpiN7HN6

Please pay attention to the fist transaction at the bottom of page.

As you can see, balance after 1st transaction is not equal to transaction amount.
Sum of all transactions is not matched to final balance too.
