You have to set up the Mistel combo exactly the same way as you do with the FW190A8 Mistel... it doesnt just come as a ready to go mix

I havent done this in a while but I think you need to set a 109F-4 Mistel + the Ju88 Mistel and then drag a target line either from the 109 to the Ju88 or other way around...
