After an absolutely disastrous evening, Destiny 2 is still unplayable at the current time of writing. The live game is down as the servers have all been taken down while Bungie deals with an issue that has been causing all kinds of problems for players.
This started following a recent and routine hotfix, which when published to the live game seemed to cause bugs that deleted progress across a variety of areas. This included Triumphs, Seals, and Catalysts for Exotic weapons.
Bungie first noticed the issue soon after the hotfix went live and announced that it would be bringing the game offline. It has now been over 12 hours and there is still no sign as to when Destiny 2 will be live and playable again.
What Bungie has stated however is that it is continuing to test to determine the issue. The developer has noted that the game will hopefully be back and alive at 11:00/12:00 GMT (12:00/13:00 CET), although that is subject to change. Expect more information soon.
