We just updated the server succesfully to 1.8, we disabled banners because of a current bug, the rest should be working as normal. Please let us know if you find any bugs.
Aside from that we implemented a temporary fix for when your prestige inventory gets reset when you change your name. This was happening ever since name changing was released and still cannot be fixed automatically. If this happens, please contact an admin to get your inventory restored in the prestige world.
