Half Slope Inv. Light Armor is not airtight when it should be.
Hello, found a block (Half Slope Inv. Light Armor) that isn't airtight when it should be. In the first picture it's flanked by 2 Light Armor Slope 2x1x1 Base and the room isn't airtight.
In the second picture I have replaced the leaky block with the same kind of block that flanks it in the first picture. The room is now airtight.
I haven't tested with heavy armor if it's the same, but it seems probable.
