So I was switching in between programs. The program i was switching to had everything in it’s hierarchy was deleted. So i switched back to my other program and everything in the hierarchy and the scene was deleted. This is becoming frustrating because everything in the assets is fine, but i have to reset the scene and everything. Any suggestions or solutions? I’m running on a Mac OSX.
Go to File->Open Scene and find what you named your scene. I think Unity probably made a new scene when you reopened your program so just find the old scene.
Hope this helps
