I just noticed after loading up a save that the quality of graphics seems to have dropped significantly. There are also these bizzare rings in the sky, which look like they are being created from notable light sources. Example: These rings appear as arcs coming out of the strip at night when it is all lit up. I'm pretty sure this is something that has only happened after this last save file was loaded. I can offer no explanation for it. Though I will say, this kind of thing should have probably been caught early in the production cycle.
