This appeared to be an issue but is now solved. I just cannot discard the topic

I was doing some UNDROPs and REDROPs and then suddenly this happened (it looked like such a well-behaved IF THEN ELSE reporter before ... and officer, please believe me, I didn't hit it): Programming tools SANDBOX script pic (14)

I moved it to a "Bugs" sprite within Snap! Build Your Own Blocks for inspection (perhaps that could help find the root cause, you're welcome :slight_smile: )

It's only a visual bug. If you reload, it goes away. I know that because the block is normal when I go to the project.

I experienced like you wrote just now. Issue solved.
