.:BUG REPORTING:. Standalone Preview Not Working

[Phant0mB0nnie]

I am unable to create map previews for my custom maps in the Standalone. I have tried the function hotkeys and they do not work. The map preview trigger option using a region also does not work. I am aware that a large map may sometimes disable making a preview, but on a test map containing only a player object, a region, a timer, a trigger, and an engine mark the preview function still does not work.
