Check my sig for the merged 1.8 mission files. Then you can remove the code you need to from that description.extMy default 1.8 description.ext doesn't have that section in it, but does have this line:
#include "\z\addons\dayz_code\system\mission\description.sqf". Should I put a copy of that in my mission PBO, change the path and remove the sections as listed in the instructions, or just comment out the line in my description.ext?
