Ya bro, make some "unit appear zones" trigger on "part of coalition in zone" instead of the flight leads.
What happened before was - I was hawg11, got empty ammo, went back to base, my buddy was on his own. He got a new task and saw nothing at the "seal team in danger, kill armor around it" task. They only showed up when I was kinda close.
Also - could you use SLmod for stuff like "we are winchester"? Because if we play the mission on a dedicated server we never see the "other" radio options.
All you have to do is -> install slmod, it's easy. Just put files into the folders and overwrite.
Then you have to make a lua script, it's easy. I have attached one to this post. All you have to do is - trigger once, time more 1, run script file. Done. slmod_magicBactria.lua
