So since the patch yesterday I've noticed that the heat system causes a memory leak and crash. It only occurs when multiple parts become partially overheated(the little meter overlay appears). As soon as two parts reach this state, memory use starts increasing by multiple megabytes/second until the game reaches 4GB of allocation and crashes. Also the parts never cool down. I can reproduce this at will, with or without kerbal engineer installed. Screenshot is attached for reference. Running steam version of ksp on windows 8.1.
