Destiny: trophies and achievements are not unlocking, how to fix it [PS4-Xbox One-360-PS3]
Many users are reporting the inability to unlock several Destiny achievements and trophies that seem to all intents and purposes buggy.
Fortunately, pending an intervention by Bungie, word has spread over the net that it appears as a remedy that in most cases works. Here's how to proceed:
from the game go to settings, under logout choose change profile and click. You will be taken to the titles, select your account and then your guardian. When you return to the game you should unlock the achievement that you did not get despite having completed what is required by its description.
