I pushed out a site update today that affects how you will build or edit a Digimon Cube. 

Previously the cube system would use its own bespoke editor for creating or editing a cube but I found the features on it to be really far behind what I have on the deckbuilder here. So instead of trying to maintain two seperate systems that are virtuall doing the same thing, I have decided to merge the cube creator into our existing Deckbuilder.

Now when you want to create or edit a cube, you will be redirected to the deckbuilder with "Cube" mode enabled. Cube mode basically sets the format and rules for the deckbuilder to cube creation. This allows you to continue to use all the nifty features of the deckbuilder while building your Digimon cubes!

If you have any issues with this please feel free to report it on the bug report forums here.
