I have a save where the output of steam boilers is 92c, which is less than the steam engines can accept, meaning I am unable to produce power and therefore do any research.

Since steam carries 0 energy at 100c and increases linearly from there. I'd think it should randomize the amount of energy within a certain factor (e.g. 0.25x - 2x energy output of steam boiler would produce steam at 116.25c to 360c or .5x-2x would be 132.5c to 230c)

Yep, I noticed this issue earlier but have been slow to fix. I recommend giving yourself free steam from an infinity pipe (that's what I did), not randomizing boilers (I believe that's an option, but I can look more into it if it's not immediately apparent which one it is), or waiting until the next version.

Thanks for the update!

Okay, this is long overdue, but the most recent update should have fixed it.
