Temerature of buildings doesn't depend on temperature of materials.

Building initial temperature is fixed (around 20 C) and no depend on material temperature.

I agree completely that it is odd. Without a way to filter which materials you use by temperature, fixing this will be nigh impossible. I spent 60 cycles once (before I learned how to use debug) getting myself ready to build some stuff out of 500C materials. That's when I discovered the "capped at 45" issue.... Ugh.....  It was frustrating, and a waste of a day. 

If they don't address this, it would at least be nice to have it stated, somewhere in the game, that this is happening.
