Hi, I speak sometimes with the guys from FFAAmod.
The main problem they have is that there are very few people, when they started with the map I think it was in the time of arma2, then they used jbad buildings.
The Spaniards are a lot of football, and things like that. Then you have mass games like call of duty battle field etc, that lets the Spanish community of arma3 be tiny.
I do not know if they do not know how to find collaborators in the arma3 community and not only in the Spanish community to work in the FFAAmod and lithyum. You could propose to collaborate to see what they say.
Now, for example, I am having problems with the mission of rescuing the pilots of a downed helicopter (no helicopter or pilots appear). And I know they're not going to make it compatible with alive because if it's just a person who is dedicated to working on that, he does not have time to investigate compatibility with a third mod.
