Hi I bought a skybox rental. I just wanted to try it ou......t its an expensive but beautiful skybox . I paid the rent and tried to move in but everytime I put down an article like a plant or couch the items would be put back in my inventory. So ...do I have to buy land to put this on ? if so how do I go about placing the skybox somewhere? I need all the help anyone would be willing to give. I am fairly new so please try not to be too twchnicle about it or I just wont understand Thanks in advance for any advice!!Zoiza
