I could be wrong, or just missing something, but this math doesn't add up to me. As a player, I read this as saying the base value of 348.2 (for the structure type?) Minus 20 (due to made of lead) should equal 328.2 degrees? but its reading that it overheats at 55 degrees... I'm at a loss. If I am in the wrong and reading the values incorrectly, could you please clarify them so that they are a bit easier to understand?
Build Duplicant Checkpoint out of lead.
