Right away i builded away from the start,
Placed an manual airlock in a spot and deconstructed it right away because of oxygen.
However, as soon they were done demolishing the door there sudden were alloy bricks....
Just look at the name of the bricks.
Not sure iff intended or in need of fixing.
P.S. i know the steel door is already posted on a horizontal door but mine was vertical as you might see in the example.
Went out mining, placed manual airlock between ignious rock and a granite block and deconstructed it.
