Yes, you read that right; %15. It's a bug that uses the “” character. It's not a space character, it's a glyph named “Negative Acknowledge”, and it has a Unicode value of . This bug can literally delete most of the blocks in your projects. and here's how to do it:
To make it even more insane, you can delete the sound tab as well. Here's how to do that.
Now you have successfully confused your teacher. Give yourself a pat on the back

- Open the Scratch website and search up “%15”
- We don't mind about the results, but just copy the character in the search bar (incase you forgot, it's “”)
- Create a new project
- Go to the sounds tab, and rename the sound to that character
- Go back to the coding tab. You can now see that ALL but the motion, looks, and sound categories remain, but there is only one block in the sound tab
To make it even more insane, you can delete the sound tab as well. Here's how to do that.
- In that same project, go to the costumes tab, and rename all of them to the character (incase you forgot, it's “”). Don't mind if it has two or more sprites and it becomes “”, “2”, “3”, … "n"
- Go back to the coding tab. You can now see that the sound category is gone. Somehow, the looks category has four blocks.

Yeah, this isn't new. This has been a problem for years, and the ST knows about it.
The issue is that the % character is used internally in defining blocks' layout, and isn't escaped when you create a custom block.

I think Bignate misread your post. This bug also occurs when you type the % character in a custom block. This specific glitch may be unknown previously, but % has been causing issues in the editor for ages.…

If you typed %15 on search, weird character appeared on the search bar. If you copy this character, and put in variables, variable did not appear, but if you go to costumes and back to code variable appeared, but all blocks disappeared. This is weird bug happends in 3.0. This bug must to be fixed in 4.0. If you find more bugs and glitches with %15, please quote my comment!

“” can also be used for more tricks. If you type this symbol in a custom block's name, you get that hidden red block thingy, and if you put “” in a name of a variable, reset it , and your code dissapears

type %15 in the search bar, copy the symbol, then name a variable that symbol, then when you make another variable, there are no blocks that let you change it, making all variables USELESS!

this is a neat bug, but it may confuse some people trying to use this character in their sprites and stuff i guess…. i dont think its very urgent to fix though
