First of all, I love the work you're doing with this. I came across it about a week or so ago and after initially downloading v0.5.8.103 and being unable to set up a game on the scene editor page I downloaded v0.5.8.74 and that worked fine so I figured it was just a bug with v0.5.8.103 that would get caught by the next version but now after trying v0.5.8.147, I still can't set up a game on the scene editor page.

What's happening is the scenarios section shows up fine and I can click the different scenarios and the villains show up so I can choose between them but none of the Standard or Modular sets show up to choose from. After taking a look at the browser I noticed two errors showing up. One related to being unable to load 'card_statistics.js' as a module script because the server responded with a MIME type of "text/plain" and one related to the createScenarios function in the scene.html file (specifically parentElement being null).

After commenting out this section of code that was throwing the error..

if( key == "Weekly Challenges" ) {
            summary.dataset.total = sets_json[key].scenarios.length
            for( let text of sets_json[key].scenarios ) {
                if( file_names.includes(text) ) {
                    document.getElementById(text).parentElement.style.display = ""
                 }
             }
         }

..I was able to get the Standard and Modular sets to load on the scene editor page but still get the error of the page being unable to load 'card_statistics.js' as a module script and once I select villains/sets/hero and click play game, the new game pages opens up but doesn't load anything and shows the same module script error but this time related to the 'marvel.js' file.

It looks like nobody else has mentioned encountering this so I'm sure it's a problem on my end but after trying it in multiple different browsers and getting the same error in each of them, I can't figure out how to get either of the newest versions working.
