A comment about my star stacking changed how I process photos

I posted a widefield shot of the Milky Way a few months back and someone pointed out that my stars had little green halos around them from bad calibration frames. They told me to take my darks and flats at the same temperature as my lights, not just grab them whenever. I had been rushing through calibration for over a year, just taking darks at room temp. Now I actually use a cooler bag and wait for the sensor to hit the right temperature, around 20 degrees Celsius. It added maybe 10 minutes to my setup time but the background in my images looks so much cleaner now. Has anyone else had a random comment totally fix a problem you didn't even know you had?

Honestly I've had the opposite experience, I've been grabbing my darks at whatever temp for years and never noticed any difference in my stacks. Seems like something only pixel peepers would catch.
