Draygon. Each of the season 2 serie (Male, female and muscular) is in its own circle if you will. So you can use Male add-ons with the male serie, but not with female or muscular. And you can’t use Muscular with male.
You cannot use season 1 stuff with season 2 material either. Season 1 is completely autonomous.
So, if all you have is the military wardog pack. Everything could be okay, depending on what’s in this pack but you can’t rely on using what’s in the male pack since the male pack comes from a different serie altogether.
I’m sorry if you feel like I’m stating the obvious. It took me some time to wrap my head around that one and it’s been tedious so I’d rather give a hand if I can. 😉 😛
