Ok what the hell are those things?! Half of my sprites/assets were replaced and some of them too so freaking long to make! If anyone knows anything about this help please!

can you please elaborate or send a screenshot or something?

Go to my latest project I think it shows it.

Use the contact us at the bottom of the home page. There you can describe the problem to the Scratch Team and hopefully they can retrieve your sprites.

Ok thank you!
