After uploading an HTML5 build to Wavedash I get this error in the console:

```lua
Uncaught ReferenceError: EngineLoader is not defined

```

Not sure what to try next. Any ideas? Thanks

Which version of Defold are you using? Are you using a custom .html shell/template?

Defold 1.13.2 and using the default html shell template.

Edit: the build works fine on [itch.io](http://itch.io) and ‘Build HTML5’ from the editor.
