Hi
I'm regularly getting my lighting effects "bugged" after a few hours play or relogging other characters, which leads me to run the repair from launcher to get it fixed even if for a little while.
The issue is mostly seen at night, visible during daytime aswell although not so evident and affects light sources, as in, i don't see the lights affecting the environment - like street lamps, wayshrines, skills like Sorcerer's Lightning Splash usually illuminate the area a bit and so on. This can be experienced anywhere even when i'm alone inside a building/cave... and makes the game feel... "flat"

My Pc specs: Win7 64, i7 950 (stock), HD7850 2Gb (stock), 6Gb ram @ native x1080
Like i mentioned above, logging out and running repair from launcher fixes this but it's starting to become a bit annoying doing this so often and was wondering if this could be fixed with some file editing, tweaking and whatnot - thanks.
