Thanks for creating the discussion! When you get a panic, don't hesitate to create an issue instead of a discussion, 'panics' are meant to be programming errors (so my fault 100%).

Back to the point, I did a rather large refactor pushed today, and the bug you spotted should be fixed in 67a9cac on the latest image. Please let me know if you find another 😉

Thanks for the quick response! Appreciate the help and I'll report back. I'll also post to the issue thread next time.
