Hopefully fixed?

The reason I take so much time cleaning stuff up and promoting it is so that
WHEN I get a bug report like this, I'm confident I can root cause and fix it in
a reasonable amount of time. (Don't want to promote anything I can't support.)

The vague goal of the tutorial videos I'm trying to do (well, the code
walkthrough side anyway) is explaining promoted commands in sufficient detail to
get the bus number up.
