Chex Pack Doombuilder 2 Configurations If you are using a version of GZDoombuilder newer than 1.09, you will need to download Chex Pack Configurations.zip and replace your entire configurations directory, this is because MaxED updated some base configurations. Otherwise, you can use "CSP P15 mod tools, version 3.zip" Sorry for the inconvenience, eventually I hope to update the Chex Pack pk3 and config files so that you won't need to do all this. -75/jwaffe
