I'm the build menu I can select items to build such as a (any) turret. I have the mats for almost anything so I can get the item to appear but i can't just place it anywhere because I have no vertical movement. It just stays about 4 or 5 feet off the ground. I can move it horizontally though. I can't find anything on the web to fix this problem. Am I the only one who has had this problem?
