probably forked network
I have seen this a few times and I am thinking about a solution. After a restart of the wallet it will follow the longest chain. Maybe some checkpoints will help staighten it out.
There is a ticket open for some time now. The wallet is in maintenance for even longer than 3 days. It is very hard to reach someone at Yobit. I will keep trying.
Which one is the right chain?
The longest chain 130k+
Wallet does not sync for two days
last block 126042
How do I synchronize my wallet in the correct chain?
Wait until fully sync'ed, then copy over wallet.dat(and masternode.conf / amsterdamcoin.conf if you're running a masternode) from the renamed data folder.
