MetalWayner i had the same problem and fixed it by deleting the SuburbsDistributions from the mod located [Marijuana>media>lua>server>items] and copying & pasting the one from the main game files in its place located [Project Zomboid>media>lua>server>items]. I think you might have to do this every build since the one that comes with the mod is from a older verison and all the new stuff they add is not in that SuburbsDistributions. Let me know if it worked for you.
