The following one you mentioned as broken, work just fine to me: Group Manager - No issues as of the moment I seem to find GriefPrevention - Has some issues with how it manages land protection in mystcraft worlds(but this doesn't worry me), but as far as overworld protection. CoreProtect - It works for me, but the rollback doesn't replace certain blocks within modpacks, or it does replace them, but with different versions of the same block. I've tried several Multi-world plugins, but considering how forge manages the worlds. It makes it difficult for plugins to pick up the different worlds since all worlds are located within one folder probably the same file. I can get Multiverse commands working, but the worlds such as Nether and The_end all send you to the Overworld Spawn when using the /mv goto <world> command. Generating new worlds are out due to a java error where it can't find something it uses to generate them. Multiworld Plugin is the same way.
