I need help, i was making a save while the beta version came out, now it says it was made on the beta version so i cant open it unless im in beta version, and when i try to save it publicly it wont allow it, is it possible to transfer the save back to the original version?
stamps (like saves) are not backwards compatible. They are forward though, so once it goes official, you can publish. For now just keep it private, or remake it on official.
The stamp backer will back your stamps. https://powdertoy.co.uk/Discussions/Thread/View.html?Thread=6057 Also, the new version shifts the element numbers a lot so don't use the stamp backer for that. But still, the stamp backer will work with until 52 and then 53 - * Well.. Don't save on the Beta, only private saves for then.
