I fully understand why you did that. Whenever I add compatibility for Mods I go through the Item List in NEI and check out everything. And also check out eventual Worldgen, even if it doesn’t appear to exist in the Nether…
I have this thing called Wood Dictionary to automatically deal with Tree Stuff from other Mods and such. Making Logs into Beams/Planks/Stairs/Slabs, and those into Sticks and defaulting to a generic Beam/Plank if neither exist in said Mod and I dont feel like adding a dedicated Block for it.
Your Stuff was very easy to deal with and actually existed in World (Though the Hyphae could have used MetaData 12, 13, 14 and 15 of the Stem Blocks, like Vanilla Wood Logs secretly do), Netherite Plus doesn’t even have its Fungi work like Saplings like they are supposed to, and everything has the sound type of Rock instead of Plant/Wood. The Mod should just add Netherite and nothing else tbh, instead of lacking half the things it adds. I still recommend it for the Netherite things though, even though I already added Ancient Debris to the Nether myself (Even with the Infinite Bedrock Veins that can be tapped much later on).
Using Efrine was a great Idea to bypass adding Netherite, though its Lavaproofness is kinda useless on things that aren’t Tools or Armor. XD
