This bug should be fixed now. I found two root causes: 1. Rather than waiting for the game engine update callback, I handle touch/mouse input immediately (required by SpeechSynthesis) so multiple input events can trigger before the game engine cleans up a destroyed object (fish). 2. I incremented score synchronously but marked a fish as destroyed asynchronously so there was a window where another click on the fish could occur. Thanks again!
