The page crashed a couple days ago, everyone lost their "Reading" and "Want to read" lists, and also part of the "Already read". Mods were working on it and said everyone would eventually get lists back, just that it may take a little while. I know of people who have it back already, but mine isn't back yet. They made a big public post about it, and people has been spreading the word when asked bit if you don't log in often you may have missed it.
I read very unfamous stuff and i have taps on each ive ever read i also have notes andstuff on what ive watched what ive liked its a safe space you know and i barely remember what ive read or wrote which just makes it so sad my fav chapters that i marked are gone i just hope this is a nightmare and i will wake up and find everything back! its like 4-5 years of passion i might cry myself to sleep at this point
Guys. It was a site malfunction. Really, it's been explained in quite a few posts. You just missed the high point right after it happened. They said it should eventually get restored. A few years ago the site had a problem as well and they had to turn comments off for a couple of years. This is similar but shouldn't take that long, from what the mods said.

I had to come here cause its a popular one but omg guys hellp why is all my mangas gone my reading list has 10 only and my completed list shrank to 60????? What the !!! Help how do i bring my stuff back i noticed it when i saw an update on a manhwa i was waiting for and its been updating gor weeks withoug notifications so i suspected that it was a new page like a reupload or something but goah everything is gone how do i get them back my tears are flowwing.
