Im not staking ! Was ok till 19th April.
Im getting ORPHAN BLOCK/prev tx already used at..... in debug log.
Just got round to downloading shrooms_chain_windows_26-01-2018 & still weird things !
Fresh QT & start downloading chain again

ERROR: ProcessBlock() : duplicate proof-of-stake !
I've just uploaded the fresh blockchain archive at
https://shrooms.pw/dl/shrooms_chain_windows_772990_19-06-2018.zipIf you are still getting troubles syncing please download this fresh copy.
Then delete peers.dat and restart the wallet.
Please let me know if staking problem fixed then.
Thanks for that Noise23, but its still throwing errors after downloading the new blockchain file !
