...and it's been fixed!
Credit to Melroy and asdfzdfj for picking it up and coding the fix in what ...7 hours?
For the wider audience, this is now fixed in the mbin code, it won't resolve here until next time @jerry updates fedia.io which could be a few days, or even week or so depending what other changes they've made and are making.
I did not update last night - there are many in flight code changes and I’d prefer not to cause more problems, so letting that settle down for a bit before I update.
