Sorry it's in french but as i've now complete MM for Darkheart Thicket but ATT keep showing me codex of tranquil mind as obtenable but i can't use them i'm leatherworking.

Maybe you have Account Mode turned on in settings?

I'm in completionist mode but not in acount mode. I've noticed that it's not only for codex of tranquille mind but all reciepes of callygraphy un fact

Perhaps you changed professions at some point on this character?

In any case, does this issue still exist in the latest version of ATT? Many logic changes have been made since this was posted and it's likely this has been fixed.

I logged onto my leatherworker and turned account mode off and I do not see the Tranquil mind today. Looked at the code and all references point to Inscription. I believe that this can be closed.
