I recently downloaded the Atomic Age mod, and seeing as I'm obsessed with all things nuclear, Heat Management was a godsend! However, I encountered a rather strange bug when I was on a routine mapping survey to the Mun. Here's a breakdown: 1. Hohmann transfer from Kerbin to Mun SOI - Went off without a hitch, the radiators did an admirable job keeping the single Nuclear Lightbulb engine from overheating. 2. Mun Injection Angle Adjustment - Since I'm running SCANSAT, I wanted to make sure my final orbital inclination was somewhere between 75 and 90 degrees. Again, no problems were encountered. 3. Circularization Burn - Negligible amounts of dV were expended, the maneuver itself was executed without issue. 4. Bug encountered - Upon completion of the burn, the radiators began overheating. Using HyperEdit, I turned on the Heat Editor to see which parts were causing the overheat. The Nuclear Lightbulb wasn't firing, throttle was 0, and the insulator that I had attached as an extra insurance policy showed no signs of overheat. But the temperature on the radiators continued to climb. Again, the engine temperature was normal, just about under 25% max temp. Using the Heat Editor, I turned it down to 0, and the heat radiators started to cool rapidly. Turning the engine heat up again, even under about 5% of max, and the radiators turned cherry red again in short order. For some reason, this resulted in a CTD, with no crash log generated. I've got about a dozen mods installed, none of which have given me any trouble before. However, the most likely culprits seem to be either TweakScale or TweakableEverything. I wish I had taken screenshots, but it was such a humdrum mission that I didn't consider the possibility until it was all over. I also should mention that I'm running 1.0.2, which seems to be having memory leak issues at the moment. However, without a crash log I can't confirm that this was the issue.
