Currently only Creative and Journey are updated to 1.12. This means you need to be launched in 1.12 to play on those servers, but to play on Pure, Skyblock or Monarch, you still need to be in 1.11.2.
Cynixx is working on finding fixes for plugins that we currently use that are not compatible with 1.12. Once he figures out those fixes, he will be updating the rest of the server!
Thank you for your patience and Happy Gaming!
