Having an issue getting a new FruitTypeCategory to load. I have this mod in my folder, added the proper line to the map.xml under the fruitType section, but its not acknowledging a new category. Not sure if you had tested that yet.
Did you add it to your maps_fruitTypes.xml or to the <fruitTypeCategories> section of the map.xml? It may be skipping the map.xml location in favor of the maps_fillTypes.xml information.
I'll do some testing and see what I can figure out, thanks for letting me know!
