On a very big level, undoing 3 times results in resetting the metadata. about puzzlescriptplus

similarly, on very big levels, smoothscreen is not updated upon undo, which means that the player is eventually undoing stuff they can't see. Besides being just something that isn't supposed to happen, it also makes experimentation and undoing large swaths of stuff in these big levels a pain in the ass.

it's more nuanced than just big = bad (Skipping Stones To Lonely Homes, in my testing, works just fine with smoothscreen. Enigmash does not.) but I admittedly can't figure it out beyond the fact that it's probably an individual level thing and not anything to do with a game as a whole.

I don't get it. Smoothscreen is just a setting applied during rendering. The undo storage should be exactly the same as any other level and/or metadata. Why does the size of the level matter, and why is it not updated? [I'm happy to look into it, but more info would help.]
