I have been invited to play this game by a friend. I entered their registration ID when I first created my character and have now leveled up to level 40. I have received mails stating "Congratulations! You've reached Level 10/20/30/40!" and tells me to talk to Astarte with an ARKS Badge: White in my inventory, but I have not received any of these badges. I've checked everywhere I can think of and they are nowhere to be found. According to web searching, they are supposed to appear in the Pickup Storage/Temp Storage box, but that box is empty on all my characters. When I talk to Astarte and select "Invitation Reward" it shows me each of the reward tiers but when I try to claim them it says I don't have the necessary items.
