I use cubed host as a dedicated server system and recently because thaumcraft and other desirable mods were in Direwolf20 changed over to that server type. Cubed host for some reason reads Direwolf20 as either BukkitCraft (Stable) when left alone and will not work but when the .jar file is renamed to craftbukkit_beta.jar or minecraft_server.jar the jar will run, but in both of these outcomes the game will let me use items from the mod, but the world itself is vanilla.
