I don't currently have any information on when the next world will be or what settings it might have. Once I do have information I'll post up an announcement with all the details.
yo @Baudin Toolan let's do something the DE (german) server is doing. You give us the announcement a couple days in advance and we vote to decide on the artifact. That would be really nice. For example an announcement tomorrow and the world open Tuesday with 2 days of voting.
