A few thoughts after playing the mod quite a bit -
Its great and thanks for making it, I can't even play the base game anymore lol. I have noticed the Marksman class part 3 doesn't seem to reward everything properly, I get the shotgun but not the loot crate or the splatter gun perk (I think this is due to the shotgun skill not being the right rank and the perk being locked). I think some of the class quests have rewards that might have been for A15 still listed too because some say tool smithing + 20 or something like that. I like the class quests rewards but I think the golden tipped machete is too overpowered for the fighter questline, when I choose that as my first class I get an insanely good weapon that one shots almost every zombie early game even on insane difficulty. Not sure what to do for that questline, maybe just reward the golden hunting knife? Although that's more a personal preference than a bug. Also I'm not sure how people feel about craftable car batteries and small engines I personally think those should be recipes included in the base game TFP needs to find a better solution to that other than wrenching cars IMO. I'm going to add those in myself, just a thought about adding them to the mod.
