I currently have a Bibucket Mercurial Multibranch pipeline that scans every 5 minutes for any PRs submitted against master which triggers our build for those branches.

After updating our Bitbucket Branch Source plugin version from 2.2.12 to 2.2.15, some scans would periodically result in retriggering all of our PR builds even though none of those PRs were updated.

This has a tremendous impact as all of our Jenkins agents would overload with unnecessary builds.

I recently updated the Bitbucket Branch Source plugin version to 2.3.0 (most recent release) hoping this had been fixed and it's still a problem.

This issue appears to have been introduced in version 2.2.13. I'm reverting back to 2.2.12 until this issue is fixed.
