I knew it would happen.
I had a 2 hour power cut this morning 16 hours into the block.
Of course the block was found after 18 hours and I received 0 reward.
Doesn't seem fair that I used 16 hours worth of electricity for nothing and yet somebody who hopped in to Slush one hour before the block got a full reward

Fortunately it took less than 4 hours for the next round to result in a resolved block, so you got off easy on this one. Just think of it as a 24 hr block resolution and move forward. The likelihood of you having a power outage at just the wrong moment is miniscule. It just as easily could have been that your power was also restored in just enough time for you to have benefitted from a short call on the block.
