It's gone forever bro. There's no point in waiting anymore, just start rebuilding your lists again
Sorry, it's all gone, but you should check your Already Read list to make sure some didn't end up in there.
Rebuilding Your Lists:
1. Use your previous (old) notifications to add to your reading lists. (This has been tested and works to start receiving notices again.)
2. If you have any bookmarks -- re-add them to your lists.
3. Use any previous comments (topics) you've left on stories here to help your lists.
4. Use your history (clock icon) to add to your lists. (If you see nothing, click the "Show All" link. It may show something.)
5. If you have a favorite author, find a story written by them and start adding the comics listed under their name.
6. If you follow someone, look through their lists and start adding them to your lists from there.
7. If you have a favorite unofficial scan group -- use their website to add to your list. If they are defunct then use Baka Manga or another avenue to see what series, they worked on to add to your lists.
Below was created by another user to help save your lists. I use a spreadsheet, so I haven't tested this.
