So this has bugged me for a while with the Squad Builder, but a double sided card is one upgrade and not two. If I equip S-Foils on a T-65 X-Wing it should either allow me to equip Daredevil or not, it should not depend on which side of the card I equip in the Squad Builder.

Anyway, this issue has now created an even more fun bug in the Squad Builder since you can now equip Darth Sidious and Chancellor Palpatine not only in the same list, but on the same ship. I'm not sure how useful this would be, but I have the feeling that it is not as designed.
