The game side of things was not ready for this kind of scrutiny. Our lobby system had a bug where a lobby could get in a toxic state, where the game wouldn't load, leading to a black screen. This happened when the lobby host got swapped to a joining client, without any game info. Unfortunately I had written it so people auto joined the most populated lobby for a game - which ended up always being this toxic one with a bunch of people sitting at a black screen getting pissed off.
When people got in a game they realised that most of them were spewing errors. When they joined a map they had no toolgun, or spawn menu.
Fair to say we didn't leave them with a good impression.
