@RobinsonX Alright so update. Apparently the other device was so old, it needed to update twice for HyperPad to be on 2.5, strangely enough. So no, it wasn’t actually on 2.5, even though I updated. I went back and updated again to 2.5 and it works now. So thanks for your help. Moral here is probably don’t use older devices in general. Though I do realize still, the game is crashing a lot on another device, so that might be something to look into. Like randomly crashing.

The save file is stored outside the project file. So it's not affected by downloading a new version from the hub.
