The new script for rescue helicopter works fine without any issues.
The video in ,,Bomb scare at the cinema complex" mission is now visible. I knew something was not right with scripts and i was about to say, that this bug existed.
However, the soundtracks are still not okay. The ID number of the track set has to be the same in soundtracks.xml file and in mission script.
I decided to share you the zip file with the fixes, that i think you should use in the next version of this mod. There tracks start from number 41 (the same is done in mission scripts), because i thought of people, that decided to make the missions avaible with any modification for themselves (just like itchboy did with his Project Nostalgia submod). Emergency_3_Mod_Soundtrack_Fixes.zip I tested it and everything worked fine for me, so it should also for you.
