I sometimes give out the wrong info to sprouts by accident in NN and feel really embarrassed about it afterwards, due to quest locations changing between expansions.
For example, someone asked where to go to learn how to use glamour prisms, and I said there was a quest for it in MorDhona at lvl 50 (because that’s where it was when I did it back in ARR). Turns out they had changed it, and made it possible to get in Vespa Bay instead, and I didn’t know. Was told by a lot of other mentors that day to just leave NN and to stop being a mentor because of it. :< my bad, sprouts.
I still feel pretty embarrassed about it.
