I recently downloaded EDuke32, and I have both the vacation and base game grp file (Listed as Atomic Edition). However, upon loading into EDuke32, there is only the option to boot Atomic Edition. Upon loading in, I can load into Lifes a Beach maps from user maps, but not as a chapter itself. Many models are swapped as well, and generally, it's a massive mess. What am I doing wrong, or what issue might I be having?
