[DRG]

1/ we have made no changes to the dust code ( that I am aware of )
2/ I have not had any problem getting airstrikes and I just tried the same combination you had ( but you neglected to tell me the month and that can be critical to dust ) and I got airstrikes with Vis 58

I am looking into the "dust" issue now. I seem to recall seeing it recently but after all these years I tend to tune it out
