I actually cannot solve this issue since it's not on my end, but the miners...
I don't know how an invalid transaction has worked its way into pools but I can't solve it without having a large majority of hashing power.
I am not sure what to think. I just resynced the blockchain and threw some NiceHash at mine77 at my own expense, and was able to mine a few blocks, but mine77's view of the blockchain is not converging with either globalpool or [Suspicious link removed]. I am keeping mine77 stratum servers offline (so as to not waste anyone else's hashpower) until there is some clear resolution.
