They're not completely coming back, but don't touch your lists yet

Oh no, but I already added some stories I remembered that I'm reading huhu, is that a bad thing?
You only added a few, it should be fine.
From now on just be careful and save your lists off-site (e.g. browser bookmarks, spreadsheets, mangaupdates).
Especially as recently I talked to some people who had their lists remove titles they added.
::: pats ::: popcorn??
I miss my now reading list, why it's not still back huhu it's been so long ヽ(`Д´)ﾉ
