The new mechanic has issues, when you load a save the recent percent also transfer to the save, which is a problem for a new game save since whenever you load a save the percent will be high and stamina will be a problem, because of the debuff and you can't relieve yourself early on.
And also the I don't know why but, the thermostat is always on when your in a new session yes you can turn it off as intended but, I'd have to turn it off manually every session.
And yes I can avoid buying the thermostat on a new game but the bug is a problem preventing me on doing so. T_T
