MANHWAS IVE READ BEFORE ARE NOW WAITING TO BE ADDED BACK TO MY COLLECTION?? WHAT HAPPENED SOMEONE PLEASE HELP ME. IVE HAD OVER 1000 IN MY LIST AND NOW THEYRE ALL GONE
The add to list option will be fixed later I assume.
As far as what I read in the FAQs there's a specific order for the lists,
Already read > Reading > Want to read
Some users will find their reading or want to read are in the read list now (like in my case.) I'm sure something will be sorted after the initial restoration happens.

It's been months . Personally I have recovered all of mine, but a lot of people still don't have theirs. If you never rated or tagged it's likely that you won't get them back. Given it's been months since the crash, a lot of people are opting to go on with life and change lists etc rather than waiting. But it's up to you.

Are the old reading lists still confirmed to be returning? Or is it confirmed that they won’t be coming back anymore, and that we should start rebuilding our lists again?
Only rated or tagged stories were restored.
Rebuild on a new account just in case. All of the admin have neither confirmed nor denied that non-tagged stuff will never come back, but it is very unlikely.
Okay thank you for the suggestion! I’ll probably do that instead since I’ve been meaning to add more things to my list(⌒▽⌒)
