Doors heating themselves

I can vouch for this. Had it happen on doors that were locked from construction (with future projects in mind) so hadn't seen any use, and randomly their heat starts skyrocketing..

Hmm, I'll have to take a look into this further. I can confirm though that there does indeed seem to be something wrong with the temperatures for doors and airlocks. I'll discuss with the design team. Thanks for letting us know.

This happened to me as well.

Same here, there is one door that behaved the opposite way for me, a Pneumatic door. At least it turned blue in an otherwise green to slightly yellow environment. Can't confirm if it always was blue or slowly turned blue, since I only paid attention to temperatures late in the game.
