Hi, we upgraded to V10 recently. For some reason we can't seem to render a custom theme on our production environments. We had some problems with the Forms partials, so we removed them from the project. Now I have a custom theme in the Views/Partials/Forms/Themes folder. This is compiled in to the project now, so there are no razor files on the publish directory. When run from my local machine, I see the results I expected. But when run from azurewebsites, I get an exception that the custom fieldtype cannot be found (in the default theme folder).

System.InvalidOperationException: The partial view '/Views/Partials/Forms/Themes/default/Fieldtypes/FieldType.CourseName.cshtml' was not found. The following locations were searched:\r\n/Views/Partials/Forms/Themes/default/Fieldtypes/FieldType.CourseName.cshtml

I don't render the form from the partial, but in our form component we invoke the forms viewcomponent directly. (This is just what the macro does).

@(await Component.InvokeAsync("RenderForm", new { formId = Model.FormId, theme = "mytheme", includeScripts = true }))

I also updated the custom theme to the latest template found here, but there are no differences with the V9 version aside from some null checks: https://our.umbraco.com/FileDownload?id=23911

I did make sure the removed additional files at destination flag is set to true. So old files, or cache, cannot be a problem.

Any idea why it will not render our custom theme on a production environment?
