My characters that visited and completed the quests on Siren Isle this week can no longer link mounts from the mount collection tab. I removed the WTF and Addons folder and tried again, and it still does not work.
All my other characters that hasn’t been to Siren Isle yet can link mounts in the chat.
None of my characters has been able to link mounts during this expansion so might not be just related to Siren’s Isle. But who knows. shrug
Bug reports are sent in-game in any case so you should do that.
Yeah, I reported the bug as soon as I discovered it. I could link mounts tuesday night before the weekly reset. After spending time on Siren Isle and finishing the new weekly quest I noticed I could no longer link anything from my mount journal. Two characters have visited Siren Isle and both are unable to link mounts in chat.
