@CobaltYash(View Post) the only broken saves i am aware of were due to bug fixes. but the saves were more of a demonstration than a showcase. Simon and the team rarely edit existing elements unless they are in beta testing.
Of course I have played, none will be implemented, no element user suggested that has more than 1 element in it has been implemented. Just go into the coding, and change BMTL to RUST. Generally as a rule, if it breaks things, no implementation. (Note to self: is implementation a word?)
