Hi, I am currently teaching a Year 3 Scratch lesson and experiencing a major technical glitch across several projects.
Code is automatically duplicating from one sprite to others. Once this happens, the blocks become "stuck"
we cannot delete them or drag new ones. Shortly after, the entire editor freezes, and the Green Flag stops working.
I’ve attached screenshots showing the code duplicating from the Rocket sprite onto the Earth sprite. This appears to be a systemic issue rather than a project-specific error. Please advise on a fix.
