Bypassing the Link Skill Limit

So I just tried to link my Cannoneer, Kaiser, Angelic Buster, and Mercedes on top of the 12 that I already had, and they all worked.
...what?

My main theory was that this only affected characters with a Link Skill, but you clearly threw that idea out the window.

I also moved my Links back from my Mercedes to my Angelic Buster.



Hayato broke the cap for me (12 -> 13), Jett and Mihile were added after that.
