I have two LDR 5001 sniper rifles. One was Void and maxed at 331 which I had for months; received through engram. I purchased another from the Vanguard with Arc and just upgraded it to 331. Now the Void sniper is gone and I have two Arc LDR 5001 snipers: one maxed at 331 and the other like new with no upgrades whatsoever. I did not dismantle and get another and I am not aware of a way to reforge a Vanguard legendary. I upgraded the second and the first was gone, replaced with an infant sniper with a different damage type. Has anyone else experienced similar bugs with weapons? I have 2 Harm's Way heavies, a Void and Solar. If I upgrade both, do I risk losing one? This is a very aggravating glitch!
