Left 4 Dead Patch Fixes Survival Mode Exploits

The first post-Survival patch for Left 4 Dead has gone live, fixing a number of exploits and bugs introduced in the free update.

The full list of changes:

• Darkened the Lighthouse background movie and increased the contrast with the user interface elements

• Chapter selection is now available when creating a Survival lobby

• Single player coop now works correctly after playing Survival online

• The correct game mode will be set when playing back a demo

• Changed holdout server spew to be development only

• Stats are no longer updated while viewing a demo

• Correctly update the leaderboard based on the player's personal time, not the team best time

• Show the player's best time in the scoreboard

• Removed Survival exploits from The Terminal, Last Stand, The Crane, The Boathouse and The Warehouse

• Fixed tanks sometimes not spawning after 15-20 minutes
