The team are aware that the 'Mysterious Stranger Tankard', granted for taking part in Legends Week 2023 as a Pirate Legend, is currently not filling with grog! This does not affect the other Tankards available throughout 'Sea of Thieves', so please be assured that any grog-swilling adventures can continue.
We thank you for your patience while this issue is being investigated.
Update: Tankards have now been replaced following the release of 2.8.6
