1. The first set of doors doesn't have any doorknobs or handles. https://ibb.co/PwqfzBq
2. The second set of doors has handles, and some very large/random hinges on the left door. https://ibb.co/JkDtc6r
3. The third set doesn't have any handles, but I can forgive that, because we're in a spaceship now. The problem is that the inside of the doors seem to have windows, but the outside of the doors, doesn't have any windows. https://ibb.co/nwpXmtq & https://ibb.co/wr6v2g1
4. The best/most hilarious part for me. The doors have handles, but they are on the hinge side of the door. No idea how this would work. https://ibb.co/gWXDcfr
