Description

I am running on the moment a Forge server with the Mineschafts and Monsters modpack. We tried switching to Mohist because we want to use plugins, but we ran into trouble with world generation. It is caused by the 'Ore stone variants mod'. When trying to generate chunks the server crashes because of a NullPointerException: Feature placement. This does not happen on forge and also not when the ore stone variants mod is not installed, so it is most likely that it has something to do with Mohist.

How to reproduce

To reproduce run a server with the mineschafts and monsters mod pack installed (or only the ore stone variants mod, but i am trying to get the hole modpack to work). Start the server like normal, it will crash during world generation. I can provide a zip file with the forge server that i am trying to switch to mohist if that is preverred.
