All my mining transactions after 4 december marked as invalid and not accepted after wallet update to version 60028 and full resync with files deleting. Also one of the payments between wallets marked as conflicted and coins lost. What to do?
The fork Block was at December 4th - so All transactions before that are now invalid and conflicting in the process. This means also that all staking rewards for EVERYONE are not valid anymore. So pretty normal.
