I saw someone ask a similar question. So let me just share my experience.
I was getting no errors, but sometimes the unit would spin, sometimes it wouldn’t.
WELL… The issue is, if you click ON THE UNIT then it counts as selecting the unit, and it defaults to MOVE. So the reason it was spinning sometimes and not other times is… If I click on the grid square surrounding the unit, it works, but if I click on the unit, it selects the unit and doesn’t spin! Because it has defaulted back to move!
