I was trying to reorganize my house and was moving a cupboard to as close as possible to the others. I held CTRL and right clicked as close to my character as possible and the cupboard was placed infront of me. I cannot move when the cupboard is on the ground. I can pick the cupboard back up to place it again.
Not a bug. You can always place things, and this to avoid getting stuck carrying.
