Collection list gone since site came back online

Hey folks, so I had added several hundred titles manually to my “collection” tab a week or two before the site went down and now that it’s back up my other lists are intact, but that one is empty safe for one title.

Is this something that’ll come back over time or do I need to re-add these titles manually again?

Thanks for any and all guidance.

Dude that sucks, I am not sure but I think that everything that could be recovered, has already been. Unless @justin can help.
