1. I elaborated on the Disappeared in the title, It's an exotic that I had but can't use to its fullest potential even though it is literally in my inventory and it should be registered as me owning it. Quest or not a gun in an inventory is a gun you own lol. Destiny is the only weird game that I've ever played that does stuff like this and its absurd. 2. I took a very long break from destiny way before beyond light dropped. Its ridiculous to think you would have to rebuy a weapon you technically own because of a quest and even more ridiculous that they wouldn't do any more planning ahead with vaulting other than "do everything before it goes away haha" 3. The gun without the complete version is basically useless. Yes you can still use it to shoot things and as a weapon but in a practical sense it might as well be decoration. 4. It's ok to make comparisons when talking about literally anything. No game I've ever played in my entire life has vaulted content and made me worry if something I have is going to be useless or not so this is not a common thing to expect whatsoever. It's baffling to think that you can take long breaks from games and can come back to things that you own being useless because you didn't do 1 quest before you stopped playing lol.
