Why are the “edit” and “retag” links missing from this post?

Question

I saw this question - Collision detection problem - earlier and wanted to edit it, but the edit link was missing:

I thought that perhaps it was because the question was too new. However, on coming back I see that the links are still missing and that another < 2K reputation user has edited the post.

Other recent question - How to create a "flying" game - for example, do have the links.

Why are the "edit" and "retag" links missing?

Answer 1

It has pending edits but you don't have enough rep to see them. I'll approve.
