When I delete a certain block, a chunk of the on start section just disappears, too.
I can always undo, but it is still mildy infuriating every time this happens.

This happens to me too. I delete an unneeded block, test my code and find out that the code to create the player is gone. @richard (Sorry for pinging you) do you know anything about this?

i need more detail than what you’re giving me to diagnose this. any chance you can record a video of this happening? or do you have a share link to a project where this happens and steps to reproduce the issue?

I have an open On start with a lot of code in it. then, I’m toggling another thing, most probably On game update. The On start is all the way off screen. I delete something while holding Ctrl. Suddenly, the screen clips a little. When I go back, half my code on start is poof

I have the same error! I don’t know exactly how it happened, but I did take a screenshot of what it did
It deleted ALL of the variables (hover was created AFTER it happened)
as well as all of the player types.
heres the link to the project (I did nothing to it as of writing this)

@naily next time that happens, please open up the developer tools and try to see what is in the console
to get what’s in the console
- open the browser developer tools by either:
a. right clicking on the page somewhere (not the blockly workspace) and choosing “inspect”
b. pressing the F12 key
c. pressing “ctrl + shift + i” on windows - switch to the console tab in the view that appears
- send me a screenshot of everything in there

i wrote up some more detailed instructions on how to copy the browser console and other things to do when reporting a bug:

something that happened to me was I just added a new colour palette and committed on github only to find everything was gone. Got it back but it scared me.

thanks @naily! I was able to quickly figure out the problem thanks to your logs:

because of some chromebook thing, I can’t access the console log, but I can describe what keeps happening. It’s like @naily’s bug but it also affects spritekinds. The most annoying thing is that this happens like every 10 minutes. 
if this keeps happening, it will effectively make me destroy me computer, quit Makecode, and never finish my game jam game.

I am not going to lie this happened again 30 seconds after me writing this post.

this seems to happen to only some projects randomly, and it happens to most when you have custom spritekinds. It’s where every one of your variables disappear and your custom spritekinds also disappear. This used to happen constantly and seems to be happening for my coder king 5 project.

I keep getting the sprite kind deletion bug, as well as tile deletion bug, both being incredibly frustrating. Just for reference, the tile deletion bug just makes every set tile to () block go blank. I also had a really weird one this morning when it changed some to the blank blocks, and some to these white half blocks? As in, triangle white slopes that I didn’t have in the assets.
