I have logged back in to check and have not received it. I accepted the reward during the event week and still have nothing. I already had the Sunslayer sword, but received nothing for this challenge.
I have not received it either. I clicked collect and now the challenge is gone from the list so I can't collect again but I never received the weapon in my inventory.
Where else do i contact them I'm really losing faith is ubisoft I've been waiting almost a no th for this and I got nothing I got the shield the first time but after that nothing what's going on!
