Import script works, but adding it fails

Hi, I have a script which was added to the Roll20 API script library some years ago, and which I keep developing (name of the script is COFantasy). My issue is that some months ago, users started reporting issues when trying to add the script from the library. I tried it, and when just importing the script, everything works fine. But when adding it through the "Add script" button, the sandbox doesn't even seem to start, and displays the error message:  SyntaxError: Invalid or unexpected token Any idea what could be wrong, or how I could debug the issue?

That's a strange issue. Do you use any HTML Entities in your script? (&, &em;, etc)?

Yes, I do use entities: '   ≥ > < 
 ☯ %... Do you have any clue as to why entities could have become a problem?

Could it be the json file?

The script.json passes jsonlint, and it didn't look like there were any content issues. I've seen problems in the past with entities getting improperly substituted. Not sure if that's the issue.  I pointed this this thread out to the devs, hopefully they can take a look. 

I remember this happening with someone else's script not so long back. I'm pretty sure that was an issue with something the the roll20 side, and couldnt be fixed without their help.

That was Chris's script where the version number in the script.json didn't match the directory, I think. This doesn't seem like that.

No news from the devs. Anyone has any more idea what could be the reason for the errors?

I just noticed that this issue is there even for older versions of the script, which used to work fine. I really don't know what to do, now.
