for windows wallets i have to resync from scratch, and i have to do this after every restart of the wallet (tested 3 times now)
but we are not sure yet if the info page is the right reference, so you maybe want to wait anyway until we hear from devs
edit jakiman: try another restart of the mn wallet
Okay, I'll try.
Update: Just restarted 20 masternodes. Now none of them match the MN info page.
Either block is out of range or hash is wrong. I'm going to resync them from backup.
i also have a backup from a node in sync with info page from about a hour ago
just send me a pm if you need the link for download, maybe this will help
