It seems that after I finished downloading my latest mod for oblivion
(Called Lost Paladins of Divine(I think that it is this mod that is causing problem))
-and activated it, that all fire is
(including candle light and just anything that gives off light)
-giving off these purple squers.
They come out from within the fire and then grow bigger until they dissolve. It's probably the texture of the fire (the glow or something) that I am not supposed to see but somehow the game is showing it to me.
If anyone knows what I should do then please do tell
