GL, People are mining TGC at over 54 TH/s on iSpace, that's the problem. The confirmation are also screwed up again, required confirmation on the pool show lover blocks still needing 119 confs, where some more current blocks have already confirmed and also up to 119 confs pending. Same thing happened after the update before this last one. I think DEV needs to rethink the block times, it's just too quick.
Plus, there is no place to trade that I can find anyways, only exchange I know that has TGC is Cryptsy, and it's been in maint since the first fork.
Blocks are being found so fast that the background process is struggling to keep pace. As the diff increases or the hashrate drops this will sort itself out and catch up. No rewards will be lost.
