Players in Call of Duty: Black Ops 2 have identified a bug where lobbies stop accepting new players after a host migration occurs. The host migration notification is often so brief that it goes unnoticed, but once triggered, no additional players can join the lobby before or during matches. This effectively freezes lobby population growth and disrupts matchmaking, impacting the overall multiplayer experience. Players seeking full lobbies should be aware of this issue as it may limit game session availability until resolved.
- Host migration message is very brief and easy to miss.
- No new players can join lobbies after migration occurs.
