Received this error under the Mystery Box's welcome message: "Oh No! Whoops, error! Show keith this number: Array !!!"

I got the same message

The Avalanche Emporium shop was changed for the snowball fight event, so now it's not compatible with the mystery box. Buying snowballs from that shop also doesn't register the Major Drills' quest to "Restock something from the Avalanche Emporium." Hopefully it'll get fixed or removed from Major Drills and the mystery box eventually.

Oh No! Whoops, error! Show keith this number: Array !!!

I thought they were going to change the shop back to is original shop/code/form after the snowball fight??

same error for me :( "Oh No! Whoops, error! Show keith this number: Array !!!"

Got the same error message when trying to do Major Drills quests.

this really really really sucks, have to give up so many quests because of this! =/

Had this problem today, too. :< Kind of annoying when I'm trying to do quests from Major Drills and this keeps popping up!
