wooow you joined in 2006, which means you have played most of the arma series right?, I just happen to be in the same boat, never done much modding but have been always coding in Arma ^_^, but that aside I haven't got to properly import custom models into Arma, I seem to have some weird issues with the shadow geometry thing in Object builder, I'm a modeler though, will look into this since my first mod got some favorites heheheheh....
A few months ago, inside his "Invade&Annex" framework, Quiksilver has managed to kind of deal with that, @h4wek . We were having a similar issue with that flatbed truck: it could only carry a single small container at once, instead of two, even if the sizes and weights were ok for more.
I don't know how did he tweak that, but your issue might be related to that little game bug as well.
And I won't dare to offer additional suggestions, because every single incursion of mine in such subjects were ALWAYS outside the regular/original set up from the game, so as you can see in this topic specifically, I could only make them work with the help of the savy guys around here. 😎
How to turn any array into a shuffled deck in 1 line. Nice.
The brackets shouldn't even be necessary since floor random and count are all unary commands.
