There are quite a few mistakes in the original files.
One of the missions has one of the vehicles set to spawn 50m up in the air. Another has the AI set to spawn 50m in the air too and they will all fall and die. You need to change the height to 0 in both. Also the C130 mission is set to spawn too high above the ground. You need to set the c130 to -.5 m height or else when the ai spawn on it they will bounce up in the air and die. Same with players who walk on it.
For the Novy center bug where all the ai spawn in the wall and die you need to change the coordinates at the top of all your mission files. Find the _coords line. Change "center" to [7360.58,7912.64,0.001] and 5500 to 7000 like in the example below:
Code:
_coords = [[7360.58,7912.64,0.001],0,7000,100,0,20,0] call BIS_fnc_findSafePos;
This will make sure if findSafePos fails it will default to those coordinates I provided (which are in the open field next to Novy) before defaulting to center (which is in the wall in Novy). Also changing the radius to 7k lowers the chance significantly that findSafePos will fail while still keeping within the map boundaries on all sides. Since switching to the above coords I have never seen the Novy bug reoccur. And the missions spawn with better variety in locations too.
