Ah, nevermind with the no mainscript warning. Stupid User fault. I wanted to create a new level. And forgot to save. Sorry
For what i mean with Folder Name versus Project Filename is this:
There is a warning for missing Project Filename when you forget to fill this line out. But no line for Project Filename. Just a line for a Folder Name. Wouldn't it be better to call the warning "Folder Name missing"? Or the line "Project Filename"? Where it becomes confusing in this case is that there is a "Project Name" Line. And i needed a few moments to realize that the warning was for the "Folder Name" line. And not for the "Project Name" line:)
