I'm editing a project with 7 vector sprites. Each one of them has lots of code, broadcasts ect.
I was programming a sprite called binary. Then I switched to sprite friend and did some programming. When I switched back to binary, all my blocks were piled up on top of each other.
This has happened at least 4 times. I'm not sure if this problem was already posted, but I hope someone will kindly look into it. Thanks in advance!

PS: I'd upload an image, if I didn't have to go through the trouble of linking to a different website.

That glitch happened to me too, after i used this block:

([... v] of (... v))

Further i don't know why it happens. That block is pretty weird, because if i select a new sprite on the block, the screen scrolls up. And sometimes after that glitch the pile up glitch happens when you select a new sprite and come back, just like you did.

I've been using that block to check the X position of other sprites, and my screen has been scrolling up too. I'm using it in both variables, and If statements. It might be browser related, so I'll test it with Firefox and Edge also.

([ v] of [Sprite1 v])

I'm using Linux and it happens on both Firefox and Chrome. (I didn't test Edge.)

I've been able to recreate it with these steps:
1. Make SpriteA and SpriteB and fill them with some blocks.
2. Scroll down on SpriteA, and add the “X position of SpriteB” sensing block to your code. This causes the scroll to glitch up.
3. Go to SpriteB, then back to SpriteA. All of SpriteA's blocks will have glitched on top of each other.

([X position v] of [SpriteB v])

When you select a different sprite on the block, the screen scrolls up. And if you create a variable or list after that, the variable or list will not create. When you go after that to a different sprite the variable or list will create, and when you go back to the sprite, then the blocks are piled up.
