Noticing an issue that has cropped up twice on me since the last upgrade - I use doors in a vacuum to gate heat transfer to my steam turbines.
Very basic setup - thermo sensor in the steam chamber, green signal if temp > 200. Noticed that the temperature was close to 300! (should never happen)
In looking around, discovered the door is still conducting heat even though it is open. Manually closing and re-opening the door did not resolve the issue. Either deconstructing it and rebuilding, or saving the game and loading makes it go back to not conducting heat when open (as expected).
An easy way to quickly tell if the issue is present is to mouseover the door - if it's temperature is fluctuating (with game unpaused, obviously), it's probably bugged. If the door is open and temperature is static, it's probably not glitched.
Unsure - it has happened twice in the span of a few hours gameplay. Will update if I can find a root cause to reproduce.
