You think I didn't try this? 
1 and 2 attempt - synchronization that stop on random block.
3+ attempt - full synchronization, and same error after restart wallet.
And again and again. Only on 6 or 7 attempt it seems to work fine. But how long will it work? Again 5-7 days only? Something wrong in this wallet.
Hey Kum Zero, we're sorry to hear about the issues. Our support team provides frequent snapshots that will make syncing more convenient in the event that users receive such a error. You can find the link to the snapshot folder here, as well as instructions on how to use the snapshot, and how to create your own snapshots:1 and 2 attempt - synchronization that stop on random block.
