Due to that the DLC was released "Just Desserts DLC" on Jun. 11, there are new 21 maps introduced.

When a player runs with DLC, they will meet the different new maps in a single run. I think the runs with DLC couldn't be compared to the runs without DLC, so I have created a new subcategory "DLC" for those new submitted runs with DLC, and moved all verified runs into "No DLC" category.
