Mangago's data disk crashed. Only stories you have rated and/or tagged were recovered, nothing else did or will come back. All retrieved stories were dumped into your "Already read" list, you have to manually re-add them back where they were pre-crash. You can start rebuilding your lists now.
The Great Reset: Back in late January, a vast load of people descended upon this website. It overloaded the servers causing a massive crash. Much was restored. But unfortunately, the disk that held our lists was irreparable. MGOs developers worked hard, but, alas, they were only able to retrieve your books if you rated or tagged them. Those that were able to be recovered were sent to your Already Read list. You'll have to sort that list as you start to rebuild all your lists.
I know this happened ages ago but have everyone’s lists come back? Cos mine haven’t and I wanna know if there’s a way to get them back now.
