Thanks for the bug report.
Okay, I opened the issue to look on that later:https://github.com/haroldo-ok/vcs-game-maker/issues/135
Okay, one more bug squashed.
Version 0.32.1 fixes a bug where sprite/background edits where being lost if the user changed pages a fraction of a second after editing a sprite or a background.
