The default spectating system has been replaced by custom cameras set up around the track, and you can now spectate at any time from the lobby
The total lap count now dynamically adjusts to the amount of players racing (e.g. 1-2 players = 1 lap)
The epic and mythic bankshot revolver has been added to the loot pool
Extra note: The old spectating system was the main cause for weird issues like your camera getting stuck to other players, the boots overheating/buzzing, and certain gameplay mechanics just not working anymore, so the game should work as intended now that it's gone!
