I've updated this on my personal version, but I haven't cleaned anything up or done any testing yet.
Indeed, I had forgotten to mention that. Werty’s mod adds a couple zombie types to the very top of “GROUP_ZOMBIE”, “mon_zombie_age” and “mon_zombie_blind”. I don’t intend to include that in the newest release, iirc my version of werty’s mod is stripped down to almost nothing as most of it made it into the game already. I only have them on my system because I’m a sucker for more variety, even if it is tissue paper zombies that collapse when you breathe in their direction. I may simply port them over to the next release, like the waterbear and nightgaunt.
Anyway, it’s easy enough to cut the 3 lines out (2 for mon_zombie_age, 1 for mon_zombie_blind) in any text editor. Sorry for the inconvenience, I’ll do up a clean release over the weekend.
