I have copied over all Japanese/Chinese buildings that we had on the city into a new area that can be reached like the other areas through the city area portal house. Thanks to lvasold and plutomaster to help fitting them into the landscape!
I also copied the arena over so we can do spleef games again. The spleef plugin still has to be installed and tested though. Thanks also to lvasold for helping with the landscaping! The arena is just south of spawn, so no need to take a portal.
