WoW Infinite Frog Companion Glitch

Just logged on my druid to do some questing and this quest requires you to shift 5 mud puddles. When you search 1 usually the pile vanishes and you get 1 frog following you, but for me the pile did not vanish and I could search it as many times as i would like to get as many frogs as I pleased 0_o This disabled me from being able to complete the quest!
