Just Let Me In
Forge no longer synchronizes registries!
About this Mod
What is Just Let Me In?
Forge replaces the vanilla registries with its own registries that are synchronized with the registries on the server, and if there is something on the client that is not on the server it will be removed from the client.
This mod disables the registry synchronization preventing this. This mod also prevents disabling if you have mods installed that also require installation on the server.
