So apparently scratch switched the ''set thumbnail'' button position, and decided that random blocks will cause my game to CRASH. I have wasted all my day trying to resolve this problem. But now if I turn a VARIABLE (which in this case is very important for my game) THE WHOLE project crashes, like what am I supposed to do? Why the font of the coding blocks is different? Why using the editor in general looks worse?
BASICALLY, if you project freezes out of nowhere one of your blocks got glitched. It's not THAT bad, because it's totally fixable. The problem is to find the glitched block, so good luck... There you can see ONE of the blocks that crashed when activated. I have no idea why they are like this. If you know how to fix these issues, or if you are also having them, please tell me in the comments.
