Hello new here. So sorry if this is a dumb question, but i have tried searching in about fifty different ways. I Cannot find an answer. This is the issue. I have "Building Kits and other items." Ii have it loaded fine. I can use everything as i need to no problems. When i save and exit then come back to the CK everything is there except the items used from the downloaded building kit. Confuses me. Probably something simple, but IDK.
