Hi there, I was wondering if it's even possible to duplicate the original timetable that comes with a map and edit said copy. So far every time I attempt that, PC editor crashes (address 0×0000000000000094 if it helps).
No, you can't do that. The game doesn't need to know what colour and position all the nodes are, so that information is all removed during cooking. That means the editor can't open cooked timetables.
