Block reward of 616.00 MMC? Is this a serious bug?

Block #380
http://www.chainbrowser.com/memorycoin/block/0000b7f077c2689dd9107cf31f20e31ff682d07dfb150e7ee387331f51c84545/

Transactions in the block says mined block reward of total: 1232.00040000 MMC, which breaks the rule I think.

Is this a problem?
