Bungie's Slipshod Fix For Destiny 2's Game-Breaking Min-Max Glitch Spurs Suspensions
The specific method to employ the exploit involves simply running the game in windowed mode and then clicking and holding down the minimize or maximize window buttons for up to 5 seconds during events you want to sustain. This seems to cause Destiny 2 to lose track of time, and events that would happen during that period get repeated over and over.
JB3 claims that he reported the flaw to Bungie way back in July, and that people have been exploiting it even before then. He says he was told by the company that he would need to provide a video demonstrating the flaw, and that he did, and heard no response. Since widespread exploitation of the bug has been decimating the game's difficulty, he released the above tutorial video yesterday hoping that it would force a response from Bungie.

Even worse is that Bungie is purportedly suspending players who receive this error repeatedly. If it were strictly an error related to cheating, that might make sense, but Bungie's own documentation describes the "RUTABAGA" error as occurring "when Destiny 2 performance drops below sustainable thresholds." Players commenting on the announcement at Bungie.net are furious and have posted many reports of false positives, including several players claiming that they were suspended from PvP games unjustly.
The silver lining here is that at least Bungie has made an attempt to prevent players from using the exploit, and everyone who was suspended from PvP can take solace in that their suspension is at least temporary. Unfortunately, Bungie says that it doesn't expect to have a full fix for this issue out until December. In the meantime, if you're a Destiny 2 player, try not to fool with your video settings or switch tasks while playing—at least, if you want to keep playing.
