Give up bro. They're not coming back. Maybe if you tagged and rated every single title in your list. But if you didn't, then forget about it. The earlier you accept it, the easier it'll be to start anew. But if you're one of those really old users with 1000+ titles in their list, My deepest condolences. (´;︵;`)
Yk what they say, we only realise the worth of something after we've lost them. We didn't care enough to tag or even rate them and now they're gone for good. I've thought about creating a spreadsheet of my list, but i was always too lazy to do it. Well whatever, there's no point in crying over spilled milk. #-.-)

What the hell happened suddenly everything is reset I lost all my reads, reading no please give it back I can’t do this !!
