Its just that they left quickly, or in that scenario, much more likely they had an error code disconnect. I feel it though. What's really frustrating is you can't find recent players, and all too often in Trials, my teammates abandon mid match, so I can't even report them for sabotage because they just don't exist after they leave, and I always forget a player name. I know they're getting a warning on the other end for abandoning a match though too. Honestly I wish they'd just get a weekend ban immediately if the game registers they went into the menu, to hold the button to go to orbit. If its due to error code, that's just Bungie being toxic about it, but that seems to be an issue at the company. Try not to be too harsh on judging those kinds of disconnects. This game is riddled with error codes, and when it comes to exchanging signals between points there is alot that can interfere, and humans just don't have the technological means to be able to fix that, even in 2022. We win some, we lose some.
