Assertion failed. Value was false expected true

Firstly your graphics drivers are from 2016, not related but good to keep them updated. http://support.amd.com/en-us/download

The errors are with temperatures, can't see you cooling anything tho, but I can confirm it does crash on my PC so its indeed a problem reproducible with the save file.

I am experiencing this bug now, too. Save file attached!

I seem to be able to progress regardless, and I *think* it continues to produce auto-saves; but whenever I exit to the main menu, I get a "black hole" crash screen.
