[DRIFT_HUNTER]

You set both classes to locked...

pawn Код:

public OnPlayerRequestClass(playerid, classid)
{
    switch(classid)
    {
    case 0: Locked[playerid] = 1; //this one DOESNT.
    case 1: Locked[playerid] = 1; //this one too
    }
    return 1;
 }

update these

pawn Код:

case 0: Locked[playerid] = 0; //this one DOESNT.
