FYI, everyone, theneonirvana on Slack helped find a bug in bbr daemon rpc command when getting block info that caused it to report full donation amount for "donation" blocks that are the 1% dev fee. It happens every 720 blocks and is 1% of the entire mining reward, so a pool would mine one of those blocks and think it earned that donation amount, for example it would be like 72 coins reported when really the block only earned 8.3.
Because of this bug, it is like the pools have been paying back the 1% dev fee to miners, so you're welcome  

This is a bad bug that I have failed to find and knew something was wrong for a long long time. PCFiL from bbr.poolto.be has been asking me for a fix for a long time, and I could never find a problem with the pool code to explain the random loss of funds, but it was because it is in the daemon.

Here's the commit that fixes it https://github.com/clintar/boolberry/commit/f601f8373d2b09ee6c07388ba5633110b241dc17

Every pool owner really should apply this.
