I have a program that has 10 scenes (grids) that are preloaded. I have code that changes scenes when a button is pressed. The code works and I am able to draw on what ever grid I want. The problem comes from the fact that the code, change scene(), seems to free the previous scene. For example, if I draw on the first grid, change to the second grid, then change back to the first, everything will be gone. I have been looking at ways to switch to multiple grids, but it has yet to work. I have found something called reload scene from path(), and save scene(). This is the link to where I have found it.

My question is, will any of those methods work? All I need to do is have the scene not be freed when I change the scene. I appreciate any help.
