I got a new failure today, possibly related to #583:

In one of the two PRs there was a message about the base branch being modified, which might be the reason of the messages:

Sorry, I can't merge this PR. Reason: Base branch was modified. Review and try the merge again..

There are however repeated messages about required checks and being unable to merge the PR even after it was merged.
