The title and description pretty much says it all. I'm new to this lovely piece of software and I'm trying to learn how to build and script missions. I've managed to create a helicopter insertion mission and in doing so I used an invisible helipad. Since then I've been adding the @CBA, @ACE, @ACEX and @SFP (Swedish Forces Project) mods. I have no idea if this might have something to do with it but the "Empty" side is no longer available from the "Sides" list while I'm adding units.
I've removing the mods from the shortcut I'm using to start ArmAII (the "-mod=..." argument) but no difference. All I get in the "Side" list now is "BLUFOR", "OPFOR", "Independent", "Civilian" and "Ambient Life".
