This is a description of the bug: When an image is imported to a sprite, then converting it to vector, resizing it or moving it around will cause it to become a pink rectangle the size of the sprite. How can I work around this?

Doing anything to a sprite's costume in vector mode will develop the pink sprite glitch. Can be fixed by leaving and returning to the editing page or refreshing the page.
See original topic here.

Doesn't happen to me. Maybe because I never use vector.
