I do not know if this is related to your issue but..
I am working on a game using double arrays for shuffling, and it does not work when using minified export. But works fine when not using minified script.
So maybe you can try to check that.
(When only using one set of Arrays it worked fine, but now I am building a game with two card decks so I cloned my arrays and renamed them, now it only works if minified is not used)
