Mechanized door glitch

The tepidizer exploit was fixed in this major update. However, the critical exploit is still possible. 

In this video, the streamer exploits the mech airlock exploit by heating with the thermo aquatuner. This happens because when mech airlock's temperature is at the melting point, it should meltdown like every other building, however when you open and closed the door, the mass of the door got reset. In other words, You can make resources infinitely.
