Arma 3
Zombies and Demons
Remove spawners from gamelogic, add them to modules and adjust eachother.
Remove spawners from gamelogic, add them to modules and adjust eachother, or atleast add ability to sync spawners' settings to spawners.

Like I said, it'd be great, because now, the spawner's setting affects all spawners, which may be uncomfortable in some cases. (Ex. in my mission Undead Stratis, when you appear too fast before spawners will work, zombies will not spawn.)
