The custom sl element is a button. The button works fine most of the time, but sometime this exception would occur: AttributeError: 'NoneType' object has no attribute 'copy_on_change' when the button is pressed. The trigger seems to be when the custom sl element is hidden.
Interestingly, adding blank lines/comments to the file with the screen where the bug occurs "temporarily" fixes the bug, so it might have something to do with the cache.
To reproduce the bug, try this project file:
https://drive.google.com/file/d/1lJjBkD ... sp=sharing
1. At the main menu, press "Battle Test", and click 4 times to reach the battle menu. ATTACK, and RUN trigger the exception, but ANALYZE doesn't.
2. Now close the game and modify game/battle.rpy (by adding blank lines or comments), save the file, then reload the game.
3. ATTACK and RUN should now work properly.
4. Now close the game, and reload the game.
5. ATTACK and RUN should cause the exception again. Very bizzare!
This reproduction is consistent on my end, hopefully it is for you too.
The custom button screen is "btn" in templates.rpy
The renpy.register_sl_statement is in 000.rpy
