For the Combined mode you can turns Primes hands upside down and the peg on Magnus' fist will fit into them on that side. That said yes this is a disappointing release, My set does not have as many problems as yours or others but there's still so many universal issues shared between all of them that it's hard to say it was worth it for the cost even if you get the best possible version. I'll likely keep it, it might not be perfect but I wanted it to display in Combined mode and problems aside it does that well enough, still a rip though
