Fabian's Strings Quest not working.

[canibiss420]

There's a quest given by an NPC named Fabian in East Freeport in the Grub 'n Grug building. All there is to do is hail him read what he says and give him 2 Gold then you'll receive exp and faction with.

Your faction standing with League of Antonican Bards got better.
Your faction standing with Knights of Truth got better.
Your faction standing with Guards of Qeynos got better.
Your faction standing with Ring of Scale got worse.
Your faction standing with Mayong Mistmoore got worse.

I did the quest in wolf form with my 21 Shaman Iksar to gain faction with the Sir Guards in North Freeport, and the quest worked. I'm now trying to do it with my Iksar Monk but when i give Fabian the 2 gold he keeps it and i receive no reward.

Please fix this. Thanks
