Incompatibility with HaloCraft/KC's Weapons mod

[branman5949]

what happens is when i load both Backhand, Halocraft and KC's weapons mod along with CustomNPC+ whenever i got to interact with the NPC from CustomNPC+ it glitches out and/or crashes but when I take Halocraft and KC's weapons mod out it works just fine or when i take the backhand mod out HaloCraft and KC's weapons mod works fine. But I was wondering if you could make the backhand mod compatible with the mods both together
