Destiny 2 developer Bungie is recommending players don’t stay until the end of Onslaught matches due to a gamebreaking bug—just a few hours after buffing rewards for players who stuck around for all 50 waves.

Today’s Update 7.6.3.2 added extra incentives for players who run all 50 waves of Onslaught, and the patch notes also list a fix to a potential soft-locking issue involving portals. Those changes don’t seem to be the only new element in the patch, though; the developer acknowledged a bug that may cease the spawn of the final boss in the Legend difficulty.
