Bugged shadows with reflections and post-processing off
@Bluebellflora Hi! this is my first time posting here, I have experienced this glitch and tried the workaraound chaging the SSAO configuration but it didn't work. After some trial and error I found out that this glitch only happened whenever I had mirrors in the house and that changing this line (prop $ConfigGroup RenderReflectionsEnabled) to false in every setting solved the issue, now i don't have any reflections on the mirrors but looks like the issue is solved. I did this after repairing my game so the GraphicsRules.sgr file should be clean. I hope this helps and can be patched in the future!
I'm playing on a Mac (Radeon Pro 560X 4 GB / Catalina 10.15.5)
