do you have "applicable" plotter_id = plotfile names ?
also possible your mining start came right about at the time where the dev restarted / reset the testnet
Lack of communication .. Would it have hurt to inform people about testnet reset ?
SERIOUSLY DISKCOINDEV - you give us a rewind - and for whatever reason YOUR testers are blocked ? .. cant even get blockchain nodes to sync my wallet
this practially a week after planned release ^^
