I went into my "recently deleted answers" tab and found this question (which is now deleted, so you cannot see it if you have <10k rep) which I answered. I can't normally see deleted questions as I have <10k rep, but I could see this one in my recently deleted answers.
The one answer I can see is mine.
I clicked the "Improve this question" button and I got sent to this link, and this is what I see A page which says "This post is deleted and cannot be edited." and is otherwise blank.
I have tried this with other deleted posts, all with the same result.
The "Improve this question" button leads to the same blank page.
Is this a bug for me? If not, why is there a button to "Improve this question" for me if I cannot edit the question?
If I cannot edit the question, I should not see this button.
