The background scroller extension has a bug and you can avoid it by moving the “scroll background” block after the “show long text” block:

> @richard Why is the debug feature so terrible in this situation? It took me forever to find this error because the call stack is just really really wrong. You can see here that I have disabled the “startbosslevel” function entirely and it still thinks that that function had something to do with the error!

> Could it be seeing an error in one file and attributing that error to lines of code in another file? I just don’t understand why it is completely and totally wrong about what block is causing the error.

looks like a bug, we maintain source maps between the blocks and javascript and it’s possible that the maps are out of date
