gamebreaking bug when used with HoneyBee AirFLEX Series

[MattPlaysSimulations]

Hello,
I have tried many times using manual attach with the airflex series headders. it all works perfectly until I attach the front hitch to it. without manual attach it works fine as its supposed to instantly disconnect from the combine when the trailer hitch is attached. this does not happen with manual attach enabled. this causes all controls to stop and upon exiting, locks up. force closing and reopening deletes the save file.
