```

Start by reproducing the reported sequence and inspect the crash path from GameEngine::HandleAudioThread() through create_next_audio_buffer, synthesis_execute, process_sequences, and reclaim_notes. Use the provided Signal 11 traceback to narrow the invalid access; done means the sequence no longer crashes the audio thread.
