After cross-checking the files, it turns out that I have forgotten to edit the name in the moves.txt file. "Atom Heart Mother" was one of the moves of Lazor Loyra in Schwarzerblitz, which I used as a base for Heatwave - the Chaingear's super move. In the transition, I have forgotten to delete one line. I will fix it in the next update, since it's not a game-breaking feature (but it's still annoying). Thanks again for reporting.
