Someone correct me if I'm wrong about this, but wasn't the original thruster problem, on the second uncrewed flight, that the thrusters were too insulated and couldn't dump enough heat, so they overheated? So for the crewed demo, they removed some of the insulation and the thrusters were dumping heat into adjacent thrusters, once again overheating? Seems like the doghouse is a poor design, at least in Starliner's case.
