Nostalrius Begins - Quality wow vanilla realm (1.12)

Hi,

I am level 24 druid and I still don't have the quest "Lessons Anew" to get my Clear Poison.. I checked the required quest, the npc that should give me the quest, everything seems to be in order but I can't have the quest from npc.

Does anyone have the same problem? Maybe its because I did the Aquatic form quest (lv 16) before the Clear Poison quest (lv 14)? Help please, Clear Poison its important

Thanks
