Look at suprnova twitter. Problem was on all XVG-pools.  I use application for android to monitor SuprNova pools via API-key and here it show orpphan balance. Maybe i`m wrong, but as far as I know Your coins not lost, just "orphaned" and need more time to confirm by network.

P.S. From SuprNova Q&A:

Q: What is a orphan block?
 A: Coins generated by a block will not be available to you right away. They will take some time to be confirmed by the entire network before you are allowed to transfer them out of the pool. Usually coins have a confirmation set to 120. What that actually means: the network (not the pool) has to discover 120 additional blocks on top of the one found by the pool to confirm it.
