Hi, I was looking at FrancisJohn’s video on geothermal power (https://www.youtube.com/watch?v=kyoLDP2tUaI), and tried the trick for building a “spike” deep down into lava (shown off at around 4:30 mark in the video).

However, my dupes do not seem able to build through the closed horizontal airlock. Has this trick been patched out?

    Thanks for confirming this!

    I know that having just one or two tiles touching the lava surface should be enough for many hundreds of cycles, but I just know that those lava tiles will solidify in the most inconvenient moment, so I wanted to have a bit more leeway - thousands of cycles. That way I can be sure that I will stop playing that particular colony long before enough heat is extracted. :)

    For now, I made a mini-spike about three tiles deep - basically, as far as the dupes could build with a ladder built just above lava.
