as of late, im having a similar issue when I go to test mode. I still have the editor screen but my level that is semi playable in the inside where the actual editor screen would have been. It is also slowing down drastically in test mode and edit mode both. Im hoping this would some how be fixed with the new update as im sure its something to do with my level or game. It just might be more than FPSCR can handle.
I am a very blunt person. I have NO filters in communication. I say exactly what I think and feel. If you think im being abrasive, its probably a personal problem because usually, Im not.
