After solving a handful of puzzles in a category, scrolling between the groups (ex. on Taiyaki, switch between Lucid Dream and Magic Jug) can sometimes cause a crash. This happens whether the buttons are pressed rapidly or not, and its occurred on multiple GBA emulator cores and mGBA standalone.
On mGBA:
The game has crashed with the following error: Jumped to invalid address: E510F004
Usually it freezes with no error message
