We have released a Beta update for Half-Life 2 and associated games. Changes in this update are:
Fixed game play issues when starting from older saves
Fixed fisherman not moving correctly in Half-Life 2: LostCoast
Fixed bad funnel effect in ep1_citadel_01 (thanks to Filip Victor for details on the issue)
Note - This update breaks any save games that were made DURING the beta, if you get an error on load of a save then you will need to manually restart that map, the command to type is shown in the console.
