BUG: Did not receive Fenrir's Messenger skill from Beatrice in Trixion

This is a game breaking bug, can NOT continue without this fixed.
From google search and video of other people doing this quest, Beatrice was supposed to give my character a special skill Fenrir’s that goes into the V slot.

The skill never made it into the inventory, and is also not in the mail, as hinted by the purple quest instructions.

Please fix, can’t continue the game without this issue resolved.
