I am running Windows and I have been crashing Speedgrade regularly since CS6. When lumetri color was implemented in Premiere 2015, I would not touch it and I still have not touched it, as I am terrified as to how Speedgrade leaves me helpless on the controls. I felt like I had to choose which tiger to tango with and knew I could not tackle both at once. I have learned how to avoid Speedgrade's bite, but I am not immune to it. I grew to love what Speedgrade can do in regards to color, scopes, masking, starting at base film in stand alone projects (.ircp), rendering,,, and still love it. Since I do not have a Mac, I cannot simulate this 'reverts all layers back to default when open again', but I have been receiving flash hallucinations which lead me to believe I have seen something similar. I have learned that when I start to loose control in Speedgrade, it is time to save, close and re-launch. I am constantly deleting cache (system, project and GPU). I loose control when Speedgrade has eaten all my RAM, so I monitor my RAM, and when it is full, I save and close to clear the RAM. Now, I cannot always monitor my RAM, as the 'scene' takes control of my focus - the scopes, display, layers, selected clips become most important and before I know it, I notice loss of control - so I follow my method of save, close and re-launch. So, these hallucinations of 'reverts all layers back to default when open again' - it is not all layers for me, it is like my last save did not stick, it is like my last save was tied to the RAM that was flat lined at MAX RAM capacity. I go to the last clip, the last adjustment layer that I was working on to continue my work. I see the clip layer stack, I see the masks, I go to select the layer to hide and observe the difference and instant reset - lost - reverted to default. I start looking around at the clips that I had adjusted, layered, masked and they are also reverted back to default, but not all layers, I still have the majority of my work still there, just seems to be the work that was done while the RAM was swapping out into the ether (ether - the particles that fall between particles of matter). Anyways, I redo my work and try to re-enforce my method of sensing when Speedgrade has lost control, then to save, close and re-launch. My primary method of sensing is watching my RAM useage, but that is like driving down the road and looking at a road map. I am running Windows, Speedgrade 2015 and Speedgrade 2014 was the pretty much the same. I have both installed on my system, not much sense going back to 2014 as I have evolved into Premiere 2015 also.
