I accidentally deleted my last post (sorry..), but the code getting deleted issue was just me randomly getting logged out for some reason, so I just logged in and searched through version history again.
Anyway after that incident, my Makecode Arcade has been crashing (“Aw snap!”) a lot more now and I think it happens when I try to edit the code? When I playtest it’s fine, nothing crashes but the moment I place something, it crashes.
