On joining a server, which has the same Versions installed as on the client, I got disconnected with the error Mod rejections [FMLMod:multihotbar{1.12.2-4.0-build-T109}]
Multi-Hotbar, not the core mod, can be removed from the server. The issue will be fixed in the next build, but the main mod no longer has any server logic.
