Sorry to drudge up an old thread, but was looking for a fix for server crash related to installing Voxelmap on bisect server with forge modpack installed. I added Voxelmap and Effortless Building to my 1.12.2 client and server, but upon restarting the server it would crash and abort restart attempts. Removed Voxelmap from server, but not client, and everything is running smoothly. Seems like it's running with full function without the need to install in bisect at all.
