Heirloom Weapon

Hello Ea, I just came back deployment and I bought a New Gaming Laptop since I travel in the military and I dont know if its cause I switched to a different console/Pc but I dont have Wraiths Hopes Dusk Melee weapon anymore like I use to before and I dont recall what season it was but I had it a long time ago and now I dont have it anymore. Is there by any chance you can help me and give it back since I got it in a chest?
