Console log

I've added both the opac-fabric-create-support, and opac itself via ftp to my server running darkrpg 3.2.3 on mc 1.18. Could there just be another mod in the modpack causing the server to crash on inital startup?

Now I see, thank you for your help of my failure to read.

Omg that's embarrassing, yet with create-mc1.18.2_v0.4.1 added console still says incompatible version/ incompatible mods. Shouldn't it work with:

create-mc1.18.2_v0.4.1
opac-fabric-create-support-1.0.0
open-parties-and-claims-forge-1.18.2-0.8.0

?

You have the Forge file for this mod instead of the Fabric one.

You used to have the Fabric one on the screenshot you posted.

It says that you don't have Create installed. The Create extension for this mod requires Create.

Make sure it's 0.4.1 or older though. It's not compatible with 0.5.0 on Fabric yet.
