Following tutorials that use Extensions (Carnival, Health Bar, etc.) I end up with the game simulator not reflecting changes made to the block code. One work around was to switch to Python, change a number somewhere, switch back to blocks, then all my new code would be working in the game. I’ve not encountered this problem when using the core blocks.

The bunny jump I was working on now has this same issue. I can’t change velocity without editing in Python. [https://arcade.makecode.com/S91986-57898-46626-82093](https://arcade.makecode.com/S91986-57898-46626-82093)

Welcome, @BrianM !
For the bunny hop program, which velocity are you trying to change: the projectiles or the bunny’s jump? I was able to alter both values, and the simulator restarted automatically.
Does the reset button in the simulator (the button with the chasing arrows beneath the screen) also not work for you?

I can make changes to the blocks today and the simulator sees the changes, was not happening before. Not sure under what conditions MakeCode needs it’s marbles reset, and how to accomplish that.
In TEALS Github, a teacher raised an issue #19 gravity changes in code not working: “The problem was resolved when I opened a link to the project. I believe what happened was a fresh translation of blocks to TypeScript or vice versa and the correct scope was applied. So, when it makes no sense, refresh the browser.”
