### Options menu fails to clear joypad state on initialization
([Video](https://www.youtube.com/watch?v=uhDSIkXkl3g))
This bug allows all the options to be updated at once if the left or right buttons are pressed on the same frame that the options menu is opened.
**Fix:** Edit `_Option` in [engine/menus/options_menu.asm](https://github.com/pret/pokecrystal/blob/master/engine/menus/options_menu.asm):
```diff
_Option:
-; BUG: Options menu fails to clear joypad state on initialization (see docs/bugs_and_glitches.md)
+ call ClearJoypad
ld hl, hInMenu
ld a, [hl]
push af
