I'm trying to setup a server for FTB: Interactions. Since it's not in the modpack list yet, I tried to follow the guide for Uploading custom server. Upon joining the server, I see all the mods listed, but a bunch of them don't seem to be working (to include the FTB questing mod), and the world spawn is not the default island in the void.
Please help.
P.S. If it helps, I set the server up using the vanilla Minecraft option in the games list (I figured using another FTB pack to build off of would result in some weird stuff).
