Hey, so I suspected this is why I was getting the Missing ProjectName.target file error of not being able to build from editor, it would say I had to rebuild manually from source when trying. I had stupidly made C++ files.
This solved the issue of not being able to build from editor. Thank you!
But, oddly I still get the prompt to build from editor each time I open the project. It works when I say yes but it’s weird it keeps asking, thought it would only have to do it once.
