Hey!
During primal storms you get the primal core for earth, fire, water and air to hand in to Rethelsi “Lead Primal Researcher” in Valdrakken.
When talking to him you can select the option “I would like to check the status of my primal core contributions this week” and he gives you the option to check status for each one.
Clicking each options looks good except the Earth one. When you click “I already brought you a Primal Earth Core right?” he replies “You have brought in a Primal Fire Core this week. It was very generous of you. Thank you”
Notice the Fire there, where it should say Earth.
