Hi,
I noticed if you are not careful on making sure you set a directory in the “Save to folder” section to something than what is in there by default your entire Corona project will be wiped, leaving you with just the HTML5 files.
Perhaps some type of check should be added.
Also, the tooltip for both “Include Standard Resources” and “Include Default font” display “Build with support for automatic syncing of project changes to test devices”, which I believe is the tooltip for Create Live Build.
