Hi Buzz,
Thanks much for those additional details. I have just tested this in a freeroam and saw it too that the selector is indeed in the OFF position in that case -- but for a strange reason, it's only that way in FreeRoam.

It works as I've described above in the other play modes (Selector in "1" at scenario start and ready to go). Must be in some way related to the engine not being active at scenario start in FR. We'll investigate.
Cheers,
Michael
