I've been working on a Scratch project lately, and one of the sprites hasn't been showing up. Due to the project having cloud variables which could alter the project, I recreated the bug as shown: over here, Sprite 4 doesn't show up no matter what I do!

https://scratch.mit.edu/projects/307329548/

I have tried pressing show and hide multiple times, pressing “go to front”, and clearing graphic effects as well as “set ghost effect to 0”. If this isn't actually a bug, please tell me how to fix this!

Take out the “forever-show-hide” loop from sprite 4.

I tried this, and it still does not show up.

Hmm you seem to have created a line vector with 0 width. If you click “Change to Bitmap” on the costume editor it appears, and then “Change to Vector” again it stays. That probably is some kind of scratch bug.

I suspect you started with a bitmap costume, and converted to vector. This causes costumes to stop working. Next time just stick with bitmap.

When I add a sprite it is not showing up so it is confusing where is my sprite.
