Once updating Arma 3 to the latest dev ver (1.69.140658) I attempted to open up a mission on the Shapur map in Eden Editor, but it will lock up with the following error message:
"Error Undefined variable in expression: fza_ah64_cem
File fza_ah64_controls\scripting\getin.sqf, line 17"
Place an Nodunit/Franze AH-64 anywhere in Eden Editor and the game will freeze.
Game will also lock-up when entering a scenario mission that includes the Nodunit/Franze AH-64 mod. This was not the case yesterday, before I updated to the latest dev version.
Unfortunately this seems to be an issue of the mod rather than the game.
You might need to contact the author of this mod to look into this
