Not gonna say much, don’t know how it happened, a check if vanished so I was half way through recoding it then the undo deletion thing popped up so I pressed undo thinking it would bring back the code, and it froze and then restarted the app, now whenever the custom thing “Coin Block” is opened it crashes.
I have experienced a similar bug, but with a custom ability. That is probably because it had too many blocks inside.
Happens to me a lot to. Just never undo. If you want to delete something just copy it then delete it or cut it.
