Reporter did not report

What's problem you are encountering?
Custom reporters do not work. Please help troubleshoot. Is this a bug? Is my project (permanently) corrupted?

What have you tried that didn't work?
I have created a new blank project with just a single customer reporter. That worked. But on this specific project, no kind of sprite-local, custom reporter on any sprite works. Always gives "Reporter did not report" error on any script that uses the reporter. Tried saving project as a new one. Also tried exporting and then importing.

Post a project example, link, or screenshot:

See the sprite "Bear" for example with the "say anything" reporter.

I see that you modified the report [] block.

This is why, the <t> primitive [doReport V] block has to be at the top of the block definition.

You can fix this by right clicking the report [] :: stack block and clicking "delete block definition"

That seems to have done the trick. Thank you for the very quick response. I have a vague memory of accidentally opening the report definition. But I did not intentionally modify it. Must have done it inadvertently.
