This currently isn't working for 2024.13... Haven't tried other versions, it just won't import, says there's an error loading it in
Seems to be a bug in the new version of Game Maker. I’m trying to fix it now. As a temporary solution, in the oDemo object in the Create event in line 393 you need to remove “control_panel” and everything will work. And about importing, I can’t say what’s wrong, I didn’t have any problems with importing.
