Unable to export batch - Warning: include(): Failed opening ..., failed to open stream: No such file or directory

[martbase]

In the process of exporting a c56 site, clicking on Export Batch generates a warning and does not export the batch.

The problem is caused by a wrong include theme path which replaces the theme handle with dashboard.

I have tried the export with the latest core on concrete5.org (5.6.3.4) and the current version on github (5.6.3.5b1) but both have the same issue.

This is a live site that I want to migrate to c57

I believe that has to do with the issue outlined in #3
I'm not sure if it's been worked out yet, since I've run into the same issue during my migration from 5.6.3.4 to 5.7
