Ok class, gather round. Here's how to get this working in B42 until the mod is updated or someone takes it upon themselves to create a new version that fixes some of the broken features.

Copy your Necroforge folder from the location below.

C:\Program Files (x86)\Steam\steamapps\workshop\content\108600\717015179\mods\

Paste it into %userprofile%\Zomboid\mods

Create a folder in the new Necroforge folder you pasted named 42.

Move everything that was in the new necroforge folder to the 42 folder you created

Create a folder in the new Necroforge folder named common.

Activate the mod in the game.

Item listing appears to be broken as is ghost mode, but you can still do a lot with it.
