So on December 24th I was playing some strikes on Destiny (PS4) and I went to the tower to swap out some items. Went back to playing some more strikes and upon returning back to the tower to pull my MurMur out of the vault and.......it disappeared. I checked my inventory and vault multiple times and it just wasn't there. I actually have been going through withdraws because I played the F**K out of the MurMur and right when I get ready to fully upgrade it...........it pulls a "Houdini" on me. Are there any destiny personnel that can help me in my dire situation?
