It happened to me on the Plane of Earth during this year's Junethack: killing Rodney with melee combat would throw a "The save game is corrupted..." error, every time. Killing him with a death ray, on the other hand, worked. My suspicion is that this is the general Nethack4 error that all variants derived from it were suffering from (yes, each of them crashed on me at least once in Junethack, and the error seemed to have been caused by completely random things, such as dropping a magic lamp on an altar and picking it back up in Nethack4, or fiddling around with my bag of holding in FIQhack), and which has been fixed in the others (Nethack Fourk and FIQhack) with this commit: https://github.com/FredrIQ/fiqhack/commit/ad01ba21df358e09c6cfcd1f88cb31e0c7e105e1
