I had the quest "A Sword Reforged" where you have to gather materials (relic iron for me) and where you also have to kill enemies with your class abilities (Mine was void). Void is very slow to get to 100% even at a farming spot since most kills will come from your special which void only gets one shot to kill multiple enemies before you have to wait ages to try again. The materials don't take long when you know the spawns but I farmed for 6 hours trying to get 100% kills on my ability. I did. It said 100%. The box was unchecked though. I thought it might be a glitch so I killed a few more enemies and it was still at 100% and the box was still unchecked. I got to thinking, why would it say 100% and still be unchecked? I left it alone and thought it might be a glitch or maybe I just need to wait for the Armsday event because I knew that was the next step so I stopped and went to the tower to turn it in. It wouldn't let me so I figured I just have to wait til Wednesday so I got offline. I got on Wednesday excited for my exotic sword and it turns out I did not complete the quest. I don't know what 100% percent means to Bungie but 100 PERCENT MEANS 100 PERCENT! It's a minor setback and a minor game problem but GOD DANGIT! I now have to wait a WEEK before I can get what I worked so hard for all because of a dumb glitch in the game. Well, here's hoping that Bungie might actually fix this and possibly give me my Exotic sword early like I should have. I'm not holding my breath though.
