Bug: Mechjeb case exploding at spawn randomly.

When reverting to launch after explosion, mechjeb case isn't attached to the hull anymore. Returning to VAB and then relaunching seems to fix it. Strange bug indeed.
I've had the same thing happen occasionally with the MKS planetary camera. I heard somewhere that it has something to do with the fact that the part is so light.
Oh yeah might really be the reason. There are times where i saw temperature bar over mechjeb right before explosion when the ship spawned. Maybe the new heating physics are derping at spawn and that moment of heat gain is actually effecting only mechjeb since it is the only part that has no mass?
I thought it actually weighed like ounces, but if you want to experiment with the weight, I'm sure sarbian would be happy to have the data there.
Increasing the part's thermal mass may help fix some of these issues. I've encountered this issue a number of times, or something similar, where the case will occasionally explodes "due to overheating." I imagine it has something to do with floating point errors on the flux value, and a tiny thermal mass not being able to absorb the spikes in heat.
Truth is i love the tiny mass which enables me to put mechjeb on the smallest of probes without a performance hit. Tho i wouldn't mind it being 0.01 mass if that is going to fix the issue.
This will probably be fixed in 1.03 when they incorporate skin heating from DR. I know DR uses a minimum thermal mass just for this sort of problem so I would assume stock will too.
Probably worth it to wait until 1.0.3 with it's skin based heating to see how that fixes the problem.
I had craft randomly blowing up, so I installed Hot Spot. The MechJeb case was cycling through random temperatures, from very hot to very cold. Increasing the mass to 0.001 fixed the issue for me. I also made it "physics-less" and everything is working great again. This is on KSP 1.0.4, btw.
