Impossible to place a gantry on drywall

This applys for many things in this release. First building, then backwall. Why? Because reasons. 

Because they changed tiles in update. They stop gas/liquid flow in space so u dont have to put drywall behind them. Gantry possibly registering as tile.

Yeah, this one is a real bummer. I try to recycle as much of the rocket's exhaust as possible  after every launch,  and do not want any leaks into space  

Hi @schrom, @Squeegee,

Only the "tile" portion of the Gantry should mutually block the drywall.  Drywall can be built in all of the spaces around the two "solid" tiles of the Gantry, either before or after the Gantry is placed. The "tiles" of the Gantry will block space just like regular tiles, so there should be no leaks once everything has been constructed.

Ah I see, thank you for the clarification
