Anyone else encounter this glitch on the GoTY edition?  It is extremely annoying! 
The only way to get around it is to rent the original game.  I send an email to Bethesda requesting a fix, but they keep ignoring my email.

Don't get me wrong, I'm not slamming this game by any means... infact it is one of my favorite games of all time.  I'm just saying this because it is super annoying to be dozens of hours into the game and then encounter this bug/glitch.

What is the glitch? What happens?

Yeah I haven't heard of any blood grass glitch?

In the vampire cure quest there have been problems with the witch not accepting bloodgrass.

• On the PS3 Game of the Year (GoTY) edition, this bug has returned though the latest official patch is already built-in. A workaround is available but requires a non-GoTY Oblivion disc
  
  PS3 GoTY edition players currently have no way of curing their vampirism due to the above bug as the Vile Lair and other official plug-ins are not available on PSN. The Bloodgrass topic will be absent or greyed-out and Melisande will not accept the Bloodgrass even if the main quest is not completed, unlike what occurs on unpatched PC and XBox360 non-GoTY Oblivion (on the GoTY version the patch is built-in, so this bug will never occur.) A workaround is to obtain (i.e. through rental) a non-GoTY Oblivion disc and use that to play through the completion of the quest. The Bloodgrass topic can then be chosen and and the player's vampirism can be cured. (This can also happen if you bought Shivering Isles as an expansion)

This glitch sucks because you have to rent the original just to get around this stupid glitch or else you will be stuck as a vampire forever without a cure.  This glitch really sucks when you encounter it 30+ hours into the game.

Hmm that does suck. I know this doesn't really answer your question, but maybe renting the original is worth the cost?
I don't know whether that works though. I have GOTY and the original. I put the original in the PS3 the other day, and it didn't load, I assume because I have GOTY format save files.

Yeah, currently there is no way around this besides renting a non-GoTY edition disc.

I'm sorry. :/

It is fairly easy to cure it before you fully become a vampire though, as long as you know these three things:  You only get it from fighting a vampire, you can cure it with any Cure Disease spell or potion, and you can check to see if you have the Porphyric Hemophilia disease in your permanent effects tab.
That said, after every time you've fought a vampire (or every few days) check the permanent effects tab and see if it lists Porphyric Hemophilia, and if it does use a Cure Disease spell or potion or visit any shrine in a temple to become cured (within three days).
I've given more info on Resist Disease and Cure Disease effects in my help topic, so check there for more information.

Oh wow, I just got to this after FIFTY hours in. I can't believe they never patched this.

Its widely known and they never fixed it. This is a massive issue with Beth. They often abandon a game and never go back to fix it. 

 Well It is what it is.  They need to Interface with this Cutting edge technology.
Then they'll be able to Leverage those assets. Which is really a Value-add on your part.
Now if they Reach out and Socialize maybe with Viral marketing. That will be a real Game changer
Then I believe there won't be a Disconnect between the players and the developers.
 
 

Agh, so I went to Gamestop and traded in Final Fantasy XIII in for 15 bucks which I bought a week ago for 60 (game sucks) to try and fix the glitch by putting in the non-GOTY disk, and now it won't even load. So now not only am I pissed at Bethesda, I'm also pissed at Gamestop for there ridiculous trade in values. 

Finally figured the fucker out. For it to load you have to go to jail and then switch in the regular version, get the bloodgrass and then put the GOTY disk back in.

Wow, this glitch sounds pretty bad. I had a glitch some hours into the PC version of Oblivion which meant I had to restart the entire game, it really sucked.
