Ok so I am completely lost on what to do at this point. I have a ship that I leave on mun drilling for ore, go back to space center, build another ship and bring it out to the mun to join the ship that is already there drilling. Once the existing ship is about 2km in distance from new ship, I get a message saying Core Overheating - shutting down; and the entire ship explodes. Or if it doesn't, the entire thing is red hot and several parts will explode, crippling the ship. I have radiators everywhere, wayyy more than what is needed to cool the drill.
AND this even happens if the drill isn't even running! I can have the drill fully retracted, the ISRU shut off, the whole ship shut down, and it still overheats and explodes every single time...
Anybody else experience this or have any ideas?
