Shaders not always auto saving

Questions
1

I’ve been working on a shader in the shader lab and the last couple of times I returned to it after being distracted for a longer while, I find myself looking at old code.

Do I need to exit the shader lab, or how can I make sure my last changes are being saved?

@Kiri this is a bug, but exiting the Shader Lab should force a save which might help work around it for now.
