I installed both part 1 and part 2 (from the workshop files)
I checked if my part 1 file was in fact in steam/steamapps/common/Insurgency2... and there it was.
But every time i double tap on ,,operator the game,, shortcut it reads it as a blank icon that says the specified path does not exist. Check the path then try again.
And yes,i repeat again... It's not my mistake,the operator files are in Insurgency2 folder!
