Bug: Lighting magics dont appear on screen!

Hi, guys, it is my first post here, and I am writting because I realized something very wrong is happening with my game. The lighting magics simply dont appear in the screen! When I use the Lighting Spear, my character is shown with his hand empty and nothing seems to hit the target. I can only see the yellow shadow of the lighting and the creatures dieing, but the Lighting Spear itself, is not shown in the screen. The same happens to the Titane Demon, I saw videos in youtube, and his magic is like a ball of thunder, but for me, I nothing appears, just the shadow of the magic in the floor. I have been playing for 25 hours now, and I just realized that there was something wrong because I saw videos on youtube.
What can I do? I searched in google but I didnt find anything like that. Maybe I will uninstall the game to see if the problem is fixed, but then I would lose my saves.
Help me please, this bug is very dissapointing.

PS3? as it stands right now there is a bug occurring that is hiding/blocking all magic and summon textures so that they are invisible, they is likely a patch in the works.
All I can advise is for you to either try and cope with this handicap and move on or stop playing until they release a fix.

Or just play off-line.

No need to reinstall game. It's not only your game that is infected with invisible stuffs.
