1: There's currently no caching on public.

2: The air vehicle check got removed because it was causing a double spawn. The infantry would get dropped in, then the heli would fly off, and then it would spawn enemies, which obviously is bad. The altitude check was doing the same thing, we just never noticed it before because the restrictions on the heli used to be more severe.

3: In theory it should only spawn when something stays nearby for 15 seconds, which usually a plane wouldn't set off. However, the trigger itself goes up to infinite height so there could be some merit to making this finite and just hoping people don't like to spend time on massive hills.

4: I literally had 0 knowledge of anything script related prior to becoming public manager, so don't expect miracles. Documentation is

I have more to say but as usual I have been interrupted by a medical emergency, I might continue later

Try again at some point, I went through and trimmed out some bits that weren't needed with our current design and our public last night had very good performance on the ground
