I went to Xur to buy an exotic (the usual) and noticed that Patience and Time could be upgraded. I was really happy, I was finally about to have a fully upgraded exotic (I'm a noob). My excitement was short lived though. After I had made that purchase, I noticed that my existing upgrades for the weapon had disappeared, as well as all of the 7561 glimmer that i spent. I was extremely gobsmacked at how something so exciting can ruin a game so quickly
