General Fixes
Fixed a bug where cavalry would receive a charge bonus ad infinitum under certain circumstances. Removed a command line cheat that would unlock the camera giving an unfair advantage on the battlefield.

Singleplayer Fixes
Reinforcements in campaign battles now appear in the order selected in the pre-battle screen. Kings will no longer die of old age at exactly 56 years.

Multiplayer Fixes
All multiplayer players will now appear in the Medieval: Total War chat room and can talk to one another. Please note that Medieval: Total War games will not show up for Viking Invasion players and vice versa. The occasional crash/lockup bug when a player quits from a multiplayer game has been eradicated. Savegame formats are not affected.
this is wot the patch fixes
