Actually, what they said was they had no new reports of this happening.
They fixed the initial bug - but that is a different discussion than undelete being taken down.
If you have a way to replicate that bug NOW, by all means, please do post it in our Bug Forum with as many details as possible for QA.
We still don’t have an ETA on undelete coming back, but I do know they’ve been working on it. It’s quite a bit more complex than ‘just turning it back on’.
I would ask that you stop reopening/opening tickets on this. There is nothing that a GM can do to assist, they won’t have any more information either.
