PR missing, causing "Pull request creation failed. Validation failed: A pull request already exists"

In my WhoDidITalkTo project, I’ve been generating merging PR’s without a problem (21 closed PR’s so far).

Until today, when I tried to create a PR for the branch “add-deploy-instructions” and received the following error:

“Pull request creation failed. Validation failed: A pull request already exists”

However, when I browse to the PR (#73) it doesn’t exist.  Even though there’s a button labelled “View #73” when I browse to that branch in github.com.

Best I can guess, I created the PR a while back, forgot I was still working on it, and somehow deleted the PR.

Now I am unable to create a PR for this branch, leaving the commits in limbo.

Does anyone have any idea how to resurrect a missing PR, or override the GitHub validation check?
