There’s a new bug in Destiny 2 that’s already messing up some players’ weekends. The Trials of Osiris tournament has started up again, but an issue with the game means some aren’t getting their loot rewards as they work through Destiny’s toughest PvP challenge.

Bungie tweeted that it’s aware of the problem and investigating the issue, but we haven’t heard any details about when it might be fixed, or what that fix might entail. The GameSpot Trials team ran some matches on a card earlier today and confirmed the loot drop bug.

The Trials of Osiris is a multiplayer challenge in which teams of three take on intense PvP matches with the goal of winning seven games in a row. As you work through your “Trials card,” which tracks your wins and losses, you get rewards at three, five, and seven wins–so even if you don’t have a “flawless” Trials run, you still get loot if you manage to chalk up a bunch of wins before you hit three total losses and have to start over.

The bug means the rewards, which are Trials-specific guns and armor, aren’t appearing, which pretty much removes the incentive for diving into the super-tough battles of Trials. What’s unclear right now is whether Bungie will be able to retroactively give players the rewards they should have earned for their runs once the bug is fixed. If not, this weekend’s event might be a wash for many Trials competitors.

We’ll update this story as more information becomes available.
