Shawn Charlesworth

My name is Shawn Charlesworth and I am in need of some help that I can not find and answer to in any of the knowledge base's. I was coupled with Casie Redrose and we had made a group called Shawn and Casie's Place. We have separated and we both deleted ourselves out of the group before taking the land we had owned out of the group. Now the land is stuck in the group and neither one of us can figure out how to change the land so it is not locked under that group. The land in on the mainland and the location is 144,212,63. It is on katakana property. Please if there is anyway you can help or at least tell me what I should do it would be greatly appreciated. Thank you again Shawn Charlesworth
