As stated, the removal after time ticks worked so far on a small island map, but might not visible planes and ships (only smoke visible) related to the script?
I don´t think so, cause the planes also disappeared, without using any script at all, if i remember that right (spent around 20hrs testing on that script so far

).
Furthermore I would need to know if the script in submission 1 removes AI from Submission 2 also? I couldn´t really find out while testing, because at some point i reduced mission times and removal times to only 10-20 seconds for better testing and it became a little confusing in the end. (Besides you are getting nuts after so many hours testing...

)
