This is caused by two conflicting PRs being merged at the same time [1][2]. The reason why this is possible is the following: A PR will be always be rebased on top of master if it gets a new commit. GitHub stores the result and shows the PR as successfully validated. If there's a new commit being pushed onto the master in between the time the PR validation has started and the PR gets merged, it will not get validated since the old check is being reused. Most of the times this does not cause any problems since most PRs are not mutually exclusive, but unfortunately, we just ran into this problem. The bring the master back into a stable state (I have had 30 test failures on my test env and all PRs will fail), I created a revert PR at [3]. After this PR has been merged, all PRs should pass validation again. Please excuse the inconvenience.
