While doing Maleria's quest, she asked for Telenine Sword. I bought it and returned it to her. Once I hit Finish Quest, a My SQL error occurs. I refresh, it says I'm still on the Telenine Sword quest. I buy another one. Rinse and repeat about three times. However, I was able to gain a Maleria's Little Helper achievement through the My SQL error. How can I complete the quest?

EDIT: And with 6 minutes left to do the quest, I tried one more time. It totally worked. Very strange. Guess this issue is fixed? Thanks!
