A couple of weird problems

[Aiight 0]

Ok, I'm designing a new mission, and I think I have everything set, except I need to place an ammo crate. When I try, it places it, but says

"Only 12 units supported on each side!"

and it also has disallowed me to preview the mission (by removing the preview button entirely).

Whats up?

In one group can be only 12 soldiers. Check every group on your map (soldiers and vehicles linked by blue line). Have on mind that in vehicle is crew. That is why you can have only 4 tanks in one group. Each tank has 3-men crew.

Error message with 12 units should popup when you place anything on map.

Yep, maybe the ammo crate is grouped to a person, so ungroup it

or you can just create an civillian or Empty ammo box..

SO it sint grouped with anybody

Once this problem is fixed you'll be able to preview your mission again.
