I have recently built a treehouse i wanted to upload it to xstreet with the same magicbox i used before. I put the treehouse and accompanying items to a box. And dragged and dropped the box to magicbox inventory. After syncing the magic box with my store nothing comes up. I have realised puting other items into the magic box works. But somethings wrong with this one. I noticed when i right click the item and say properties inside the inventory i dont see myself as the creator. But when i rezz it on my land and right click edit it i see myself as the owner. Please help. Im stuck
