So I'm paying for just a small 15 slot server with 1GB of RAM. I used Multiverse for awhile, both Core and Portals together, and my server would occasionally freeze up and crash. After talking to my host, they told me that my server was running over my 1GB, so I got rid of MV. I noticed immediate results and now my server is pretty much lag free. However, I'd really like to have at least one other world to play in for creative mode. The only up to date plugin I've found is Multiworld, but it has a lot of issues. I can't add an already existing world to it. It auto-detects the nether and the end, but not my creative world, not to mention it doesn't generate a config file for me to edit. So I really need to find a working multi-world plugin that isn't too intense on resources. Anyone have any ideas?
