Two days in a row I have not gotten the instance key after finishing Orim’s Sin. Please look into this.
I have found that if I had a left over key from running another instance, my key disappears and I do not get a new one after the current instance is complete. Doing normal on my elf, I can kill Orim very quickly, so the prior instance key didn’t have time to automatically disappear. It seems like it deletes what I had in my inventory and never puts the new one in my bag when I finish the Orim instance.
That may be what is happening to me. I’ll have to check for extra key(s).
