Hi BPANDREW -
I want to clarify a few things to make sure I understand your issue. Is it the auto-save function which is always running or when you hit save and it will not stop saving? Does this slowing because of updating and saving assets occur when compiling blueprints or materials or only when you save the level (*.umap file)? Also, what was the last development you did in your project before this issue started to occur?
Thank You,
Eric Ketchum
