Not sure if its related but I haven't gotten a nmc payout since the 8th. Also my min payout amount was changed from .1 to .03. I can tell you for sure that I did not change my min payout since I haven't opened my bitcoin wallet in weeks so I haven't been signing messages.

If its any help wizkid I can get you my address i use to mine to check logs etc.

EDIT - I also had set donation amounts and they also changed to 0.0.
