I think we might need richard here to solve this one…
Basically what I was doing was I was making some array stuff in blocks and I needed to start working on a placing mechanic. I removed some blocks to make sure that there was nothing to start. Then I needed to switch to javascript to add a special object (eg. null, undefined). But the second I did that, my entire project broke and gave me 10 errors.
Heres the project link

Did you also happen to remove an extension, by any chance?

If you change the start timer line to:
let startLocations: number =
Then you’re just left with the timer error.
