It happened to me as well!! OMG! so its not my delusion!
this is just a guess but mangago seems to also have an automated bot that crawls on other manga sites and automatically copies any new series.
chapters with blank uploads are automated while the ones with usernames beside them are uploaded by an actual mangago user. that's why there are duplicate series on here, and sometimes an official uploader requests a duplicate to be deleted to have their upload as the sole source.
so, bad luck if the one on my reading list happens to be a bot auto upload that got deleted :(
It’s lokey upsetting though cause I had like over 1000 in my already read between 1350-1600 and now I only have 700 and that’s where I put all my favorite ones that I’ve read :/
I honestly thought I was going insane lol. Does anyone know how to fix this?
Oh my! It's like a premonition, I should have back up my list when I started 2023, coz this 2026 I lost thousands!!!
I thought It was only me, This past months My already read list has been decreasing even my bookmark does TwT It only saves for a few days weeks later when I try to find my recently Already reads only 1 page is recent and the rest are months ago even though I already marked alot of manhwas done :'((
like i'm pretty sure i added the manga a couple of months ago, but then i see it on the recently updated list- and when i click on it, it shows it's no longer in my list. this has been happening for a lot mangas. i wouldn't even know they got removed unless i saw them on recently updated..
like, is this a case of mangas being reuploaded? does this happen for anyone else?
