Here are screenshots of the radiators acting weird, and topping out earlier than they should.. Most of the time they work but, here are 2 times I caught them getting stuck. 1584.2K seems to be the magic number. - - - Updated - - - I have one other breadcrumb... When these craft have their microwave receivers on, they have the bug, as soon as I press the hotkey to switch them to relay's it goes away. If I activate the receivers again the bug immediately reappears and the radiators jump to the lower temperature and lower heat dissipation. Receiver on -> Capped at 1584.2 Relay on -> Acts correctly Receiver back on and relay off-> Capped at 1584.2K again and heat dissipation falls significantly
