Wolf0 has been a valuable contributor in slack, examining code and answering questions - he probably put in tens of hours to add to the discussions.
The bounty was created for a solo miner yesterday and the dev contributed 1000 pasc. 3 or 4 others contributed the rest including herman's 500 pasc. Wolf0 made the solo miner and successfully claimed this bounty. Everyone in slack saw the whole thing happening.
Looks like a misunderstanding happened here. The dev has been honest and transparent throughout.
