Quick note about Guild Roster issues (where it’s appearing empty)… no data has been lost on the server, so no need to panic… it’s just a display issue!
Currently, it seems that players on the OLD servers are experiencing this. No idea of the cause yet, but killing off and restarting the mobile app should force you onto the new servers and fix the issue.
On Steam - sorry guys - no news for you yet… though we’re investigating fast-tracking your migration so you don’t experience the problem any longer than you have to!
