I did submit a ticket about this, but after this morning’s maintenance all of my druid’s reputations reset. It’s as if I am on a fresh character. I only noticed because I was pvping at maraudon and tried drinking my AD reputation food and it says I can’t use that - then on the food it says requires friendly. I’ve been using this food for months.
I also have the ZG exalted neck in my bags but I just used a token to test it and my reputation hit neutral with the Zandalar tribe - so everything is actually gone. My Darnassus rep is 1000, Gnomeregan/sw/IF are all 100 as if I am a new character. I have a warlock on the same account and her reputation is fine - she can still use the mana biscuits from AD. This is just affecting my druid on the same account.
