[Bug] Changing Level Name When Level Is First Build Level - Causes Build Crash!

OK You rename your main level, do some other stuff and everything is working fine in the editor.

You build run and crash, the change to your first levels name has not been propagated when you changed it checked for when you build!

Probably best to check for and offer fix in build as there is bound to be someone who tries to change the first level by renaming!

Keep up the great work.
