Helium 3 was accidentally removed at https://github.com/OmnifactoryDevs/Omnifactory/blob/d6244b93354c31006f9a413b7ae292470c29232b/overrides/scripts/Nuclearcraft.zs#L397 when it should be removed in the sharedFluids section, as helium 3 is a shared fluid between gtce and NC. Removing here breaks the H3 cell recipe, which is used in the Empowered Enori Gear, and it also makes the H3 output from the Lunar Mining Station seem useless.

Yeah that was an oversight. Fortunately it's simple to fix and you can solidify the empowered gear instead of empowering it directly, so there's a viable workaround at this time.
