The only book I need for this is The Old Gods and the Ordering of Azeroth (Annotated). Today on my weekly Zskera Vault run to look for this book, and it was there. However I could not loot it because there was on in my bank. Apparently I had never gotten credit for it on the achievement. So I went back to the bank and read it, no credit. I destroyed that copy, and went back to the vault. Book was not there. It was in my mail. I got it out and read it. I still have no credit for this book on my achievement. So now I have to go destroy this other copy and back every week to the vault hoping it is there that week.
Also only need this book and it’s in my bag but reading it doesn’t give me credit. Have opened a ticket
