There appears to have been changes to the airtightness for this block. The following config used to be airtight but is no longer. There also appear to be other bugs associated with airtightness on its half-width edges as I am experiencing other anomalies with this block.
Half Slope Inv. Light Armor is not airtight when it should be.
Won't Fix
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.
Best regards

Hello Robert,
We’ve recently revisited this issue for another technical review. After careful evaluation, we confirmed that with the current game technology, it’s unfortunately not possible to resolve it properly at this time, so the ticket will be closed as “Won’t Fix.”
That said, this kind of limitation might be something we can approach differently in the future — or even overcome entirely with the technological progress that could come with a next-generation version of Space Engineers. Time will tell.
Kind Regards,
