To install, you will need either: to do a clean install of DCG v3.0 first, or else go to the settings screen and press "Extract All Maps" again. Then, simply extract this file over the Full Release of DCG v3.0. This fixes a bug which subtracted points from the player after each battle. It also fixes the crashes that occur on many maps after installing the latest patch. See the included readme_hotfix.txt file for more information.
