Well I really think Arcticcoin is dead. Dev's seem to give a shit on what users report about complains here.

Recently gave my masternode a try (after having it running without any reward and REQUIRES_RESTART State). I tried purging whole blockchain-data and did a full-resync. Masternode worked with rewards for 8 hours... then falling again in shitty REQUIRES_RESTART state.

I'm done with Arcticcoin.
