So the problem basically never went away. I have two new machines: a windows box with 32gb of memory (more than I had previously) and a Macbook pro. Both crash when editing materials, although the celshader project crashes far more frequently - about every second action inside of a material. You have to understand, this has crashed 10 times for me in 3 minutes and I’m just saving and editing and crashing, saving and editing and crashing over and over. We have to fix this.
Eric, I believe I’ve shared the project with you on Dropbox in the past - I’m working on a new copy so I’ll share that with you again. The material to edit is called “CelShader” and it’s in /Game/Shaders/CelShader/PostProcess.

Just going by the error, it’s nothing breaking, just something leading to a bad assert. Perhaps a race condition?
