This is a known bug that was fixed in PR #30296, merged on December 30, 2025. Since you're on version 1.12.1, you should have this fix if you're on a build from after that date.

The root cause was in the version history panel component—it was calling handleRestoreFromPublishedWorkflow() for all versions, including drafts, which overwrote the current draft. The fix added conditional logic to distinguish between draft and published versions.

Several related issues were reported:

  • #26107: Draft version uses wrong DSL after viewing history
  • #29938: Changes in historic versions affected current live version

Recommendation: Check if your Docker image is from a build after December 30, 2025. If you're on an older build, upgrading to the latest should resolve this issue.
