Foxhound :
Make sure to save your mission often.
Are you using the latest ArmA2 patch (1.03)?
Can you command your AI in the second mission? If so have a look at this AI Squad Command Guide.
Yep, I am using the latest patch. I had a look at the guide, i'll have to check out the videos a little later. Looks like perhaps I needed to tell the squad to move in "danger" or "stealth" mode. They did fine until it was time to move and then they would take to the street for a bullet sandwich. Reading that guide, I think I have a good idea why now.
So much to learn, and I haven't even gotten too engrossed in editing yet! though alot of videos on youtube showing the possibilities of attachTo have me itching to try it out... mobile MGs mounted on cows and mechwarrior things made of various vehicles and a C130. Too fun to pass up on forever!
EDIT:
Finally passed 02 without too much trouble. Thanks for the helpful links!
I toyed around with the attachTo function a bit and was able to come up with some bizarre combinations. Attach a bunch of mass graves and grave crosses to rabbits. It's almost halloween, after all!
Also, running around with a massive antenna array stuck to your head does wonders. Especially if you put a checkered flag on top. The editor is WAY too much fun. That much fun might just be illegal... it was hard to stop laughing obnoxiously loud before 10PM rolled around.
