There's an item bug, plus my quest is completed but the progress isn't showing.

Hi p33iqir34c1v​ thanks for reaching out! I can help with the mailbox, checking your account I see you should have recieved the item 🌱you should get it next time you log in.

Regarding your second report, this issue has already been logged and passed onto the team! I don't believe any blanket copensation was granted to impacted players, but you can reach out to customer support if they can provide further assistance.
