// Score Memory
//******************************************************************************
// This feature allows you to give disconnected players their score back when
// they rejoin the server during the set grace period. The server will remember
// and restore the player's total points, kills, deaths and bonus points.
// The rank system will automatically adjust the player's rank.
// Extremely useful when a player's game crashes, or when PunkBuster decides to
// drop players for losing key packets.
// 0 = disable
// 1 - 3600 = grace period in seconds (default 60)
//set ex_scorememory "60"
