Onovia's FTB Ultimate Reloaded server has been updated to 1.5.0. This brings bug fixes both server and client side. I've also enabled some block logging and permissions to help combat some griefing that's been going down. All users now have access to the '/pr near' command which will list all changes that were made around you. If you notice you've been griefed and want to make a complaint, please post here on the forums and an admin will help.
