I was doing a manned mission to duna (you can find the craft on my kerbalX page called Saturn Five), happily timewraping thriugh interplanetary space and BOOM! My rocket overheats and explodes.
I'm using 1.4.3 along with mechjeb, hyperedit, vessel mover, stage recovery, docking port alignment indicator and physics range extender.
I had a few other encounters with this bug. Most of the time stuff doesn't explode, but sometimes overheating bars are seen.
I know this bug happened in previous versions, but is there a solution to it? It seldom happens but still it is annoying.
