Someone has opened a wallet that hasn't been unlocked since January 2016. So he have very old coins to mint with,.... Each block he find with coins that old have a trust value way higher than standard block. When these old coins will finish minting orphan ratio will return to normal...
And as you can see, POS difficulty is lower than 2 days ago, so this situation should come to an end soon.

Sorry for the inconvenient... As a miner myself, I know how it feel to have our found block orphaned at that rate...
If you want, send me your CashCoin address and I'll send some coins on your way!
