This is rewards being sent to minincore dev address and not the pool address. 3 blocks were totally sent like this ignoring the pool address and directly sent to the BTG address hard-coded in the minincore,

Pool was set to SOLO mining with no recipients added. (Expecting full rewards to be sent to the address mined the blocks, or the pool address)
