Hello, I have a Mohist server with Forge version 47.4.13. After installing the Valarian Conquest mod and joining the server, any player right-clicks the server and crashes. It's clear that the Valarian Conquest mod is causing this, but is there any solution to fix it? I launched a test server with this mod on a new world, and the same thing happens.
