Multiplayer: Hit Detection Sucks, It always says "Need more players to balance team" even when it's free for all or when it's a full 12 player lobby.
Campaign: In "Time and Fate" Mission there is bugs where when after clearing the courtyard the soldiers are in hiding from enemy mode when there is no enemy, and when it does Woods an the other guy goes down the ladder and I can't.
Zombies: It always says "Match is Begining" forever and doesn't move when everybody is ready upped.
If you know any bug fixes please respond. If Treyarc is listening make an update.
