The lobby server is the real problem. Dealing with 4k+ queue is annoying but "normal" in a new ext launch. But waiting in a 3-6k queue and have to do it again and again because the lobby crashed is obnoxious....
100% of my 2002 error were with less than 50 player queue, i don't lost packet for 3 hours but it happen every times in the last 30 sec ?
