For anyone who is interested the bigpiece.bpm file is contained in both the aa50 41 and 42 modules. to get it to work for aae aap you just need to open the the 41 or 42 module then copy and paste the big piece file to the module you want to run it .
Unfortunately the colors and fonts are for the aa50 units in the order in which they move based on either the 41 or 42 scenario so the map is misrepresented
