ok disregard my first post.. I see what you did.
Yes I understand now. I didn't understand that this was a complete overhaul. I had thought it was only a map addition. So I called it like a regular map add-onDo not replace the mission file. Replace the Mission.sqf instead.
Those 2 are totally different things. There is no reason for the mission.sqf to be called mission.sqf though.
You can even call it WhatEverTheHackYouWantToCallIt.sqf. It does not matter. As long as you reference the correct filename in the mission file's init.sqf.
