So... I guess they let you down after all, huh? 
Anyway, that's not a formation failure. That's an MI logic failure.
...Or it's that the MI have a shorter range than the other ranged units around them.
I thought that had been fixed with the latest changes to ranged units that make them fire for as long as they have a target, rather than advance. Maybe that hasn't made it to stable yet?
No, I don't think it has. I still need to find out why the fire-into-melee bit is only doing 1 damage
