Some missions contain their on server.lua file. This will override the one you changed to fix the Simmod A-10 in E:\Program Files\Eagle Dynamics\LockOn Flaming Cliffs 2\Config\View.
If you're using W7, locate the mission in question. For example E:\Program Files\Eagle Dynamics\LockOn Flaming Cliffs 2\Missions\A-10A - A visit to the Port.miz. Right click on it and select 7-zip, Open Archive. When the Archive window opens check to see if the mission in question has a Config folder, double click it to open it, if it has a View folder, double click it to open. If there is a Server.lua file right click and select delete.
As always, back up the .miz file before doing this!
Try at your own risk!
Hope this helps!
