Profession bug ?

Hi,

Were 500 at armorsmithing and cooking, but seems that we can only have 2 professions master, that's why back at 499 ( should be 399 .. no idea ) for aethertapping and essencetapping. So just done essencetapping quest for master, but still can't up at master..
saying that i must first do master quest .. some help please

Edit : Oh just seen that 499 is still the max for essence/aethertapping o_o

 

Yes, that's correct, Aether/Essencetapping's level can't be raised to Master, Expert (499) is the max
