I just received my copy from a trade I did with a guy a few months ago. I don't think this is the full on KS copy but holy hell, the box weighs a ton. It weighs more than my Gloomhaven box, and THAT has a Broken Token insert in it plus a bunch of 3D stuff I bought off of Etsy.
I also bought some 3D terrain for Frosthaven and some helpful card draw holders too.
