I had cheats on and when I spawned a bed through using the cheat ( /give gamergal691 26 1) it only spawned as the bottom half of the bed and would not allow me to sleep in the bed. Also, you have to place the bed once and then pick it up for it to become a bed that works.

Steps to Reproduce:
1. Use the cheat the spawn the bed (/give [name] 26 1). A red square should enter your inventory labelled 'bed'.
2. Placed the bed down - it should only be the red section of the bed.
3. Break the bed, and you should be given a proper bed that works.
