I have edited questions a couple of times, and will get rejected by Community (user -1) and will look at the question and it will contain the edits that I suggested.  Is it a race condition possibly based on someone else editing the file at the same time?

Once, I figured it out, it was someone rejecting it, but another person taking my edits and proposing the same edit.  (I talked with the editor, and this is the case.)

I find it strange behavior.  And it doesn't happen often, but when it happens, The times that I have noticed it, other than the one I talked to the editor) they have had a 3k+ reputation.

But it also counts as a 'reject' even though the changes were ultimately accepted due to the result, though not the mechanism.
