Synechist, there was an issue on BLOCK wallet syncing. Is there an instruction how to resolve it?
Yes, delete and resync your copy of the blockchain. Use the parameter “addnode=104.131.176.233” upon launch (that's Dan's node) if you want to ensure that you download his chain, because an exchange and a few other people seem to have got onto a fork (but they've subsequently got onto the main chain now).
That startup parameter can ether be pasted into a .conf file in the same directory that your wallet.dat is in, or added onto the "target" field in a desktop shortcut.
If you need more info, come ask in Slack.
