Lighting Glitch

[(PSN)Herculxs]

When I walk around my dojo i see a glitch that i can only describe as a "shadow line glitch".  While walking around there are a bunch of flashing black lines that I assume to be shadow glitches. This really only happens in halls with lots of decorations placed down. This needs to be fixed because it makes the dojo very annoying and almost ugly. There are also lots of shadowing glitches that need to be fixed. Some objects either cast a super black shadow or no shadow at all, it needs to be consistent. In my Loki statue room it is literally pitch black and it is very weird. Plz fix this stupid lighting/shadowing!!!!
