Destiny players are being warned about linking their Bungie accounts with their Blizzard accounts, as some are reporting the loss of years old accounts. While the goal is supposed to be preparing a Bungie account for the inevitable jump to PC with Destiny 2, some are finding that the process doesn’t work as expected.

This week Blizzard launched the ability to link a Bungie.net account with a Battlenet account in preparation for Destiny 2’s release on PC in October. Under normal circumstances, players should simply be linking two accounts, but what has ended up happening in some instances is an overwriting of the original Bungie.net account.

It’s unclear how exactly the process works, but most report that trying to link a Blizzard account to a Bungie.net account ends up creating a new Bungie account for the individual. Then, once said player links their gamertag or PSN ID with that new Bungie account, the old one is abandoned. Once this happens there is no way to recover the old account; it is simply gone.

If the PSN ID, Xbox Live Gamertag, and Blizzard BattleTags are unlinked from a Bungie.net profile, the profile will be orphaned. This is permanent, and access cannot be granted to an account that has been orphaned.

Forums on Blizzard, Bungie.net, and Reddit are filled with accounts of players losing accounts that were years old. Bungie.net has been around for quite some time, and many have been with the Halo and Destiny developer since the very beginning. Unfortunately, one seemingly innocent process has wiped that allegiance from existence.

At first glance, it may not seem like too big of an issue, even if some gamers might have had those accounts for years. But the real problem is that transferring info over to the new Bungie account doesn’t transfer anything redeemed on the old account. That means any codes or rewards that were tied to the old account are lost, including access to the Destiny 2 beta for any that pre-ordered on PS4, PC, or Xbox One.

While Bungie may eventually come forward with its own warning, let those that lost accounts make others aware of the dangers of linking to a Blizzard account. As long as gamers are careful about what account they are tying a gamertag or PSN ID to they should be okay, but it’s best to be as cautious and paranoid as possible throughout the process. Losing a Bungie account with years of mileage on it has got to be very deflating.

Destiny 2 releases September 6, 2017 for PS4 and Xbox One, the PC version releases on October 24th.
