deck builder issues

[salyrical]

I'm not sure which update it was, but after kaladesh was released on here I haven't been able to use deck editor. No cards populate in the select cards screen and the lower areas where the deck and sideboard would be says 999 in each numbered location. Also when trying to import the following decklist I get an error of something like "line 12 mistfolk not found"
