User blog:TheRailgun123/Sim needs fixing

Okay, for some reason whenever I make a new deck on the buddy fight sim it doesn't save. I know I click the button but it won't work. I've tested it out a few times and it all came out the same. For some reason, the flag is there and my buddy as well but the rest of the deck is gone.

So, could someone please fix it? I've been watching a lot of Buddyfight lately so there are decks I really want to build.
