Sorry if this is a really silly question. I've got a chair I need to turn around and for the life of me I can't figure it out. I click on the Rotate button in the middle of the screen and I can turn it to the position I want, but I can't keep it that way. When I click on it or escape it goes back to its original position. Do I need to hit something to lock it to its new position? I'm on the PC version. Thanks!
