Naughty Dog has applied patch 1.01 to the MP which upgrades the game to version 1.05.130 for the US and 1.05.030 for Europe. The patch includes 2 new maps, Molten Ruins and Highrise, and the following fixes:
-Fixed a bug which would cause players to stop accumulating cash and items purchased
-Fixed a bug that could cause the player to lock up accessing the Friends list, or when a Friend joined them
-Removed Team Objective and Plunder kills from being tabulated against the Kills/Deaths Leaderboard (all kill/death stats are still kept locally for the player)
-Leaderboards will be completely reset soon to coincide with the above change
-Microphone icon will now appear in the Multiplayer lobby to indicate who is using a mic
-Fixed a bug in which switched control schemes were not being saved properly
-Players will no longer able to join a party that is in the Find Game function or actively in a game (was causing various issues with players not being pulled into games properly)
-European and American players will be re-integrated into the same play lists with this patch
