Hi, I experienced the following bug a couple of times :

Create a pull request from myrepo/branch-0 to upstream/branch-0 (new branch)

Everything looks fine in diff.

Lead developer wants to merge it, he and I get "We were unable to load this page." in overview while commit list is correct.

So I tried to create a new PR, but since its the same source to the same destination, it just redirect me to the old PR, which doesn't get updated in anyway.

Lead dev merged it in upstream, and now the overview is fine

Please let me know if you need extra informations
