If he uses random(MAX_PLAYERS), it's like he uses random(500), so it could be that playerid 455, which is probably not online, receives the money o.O.
Top of the script:

pawn Код:

forward RandMoney();

Under GameModeInit:

pawn Код:

SetTimer("RandMoney", 30000, 1);

Somewhere in the script:

pawn Код:

public RandMoney()
{
      new PCount;
      for(new i; i<GetMaxPlayers(); i++)
      {
            if(IsPlayerConnected(i)) PCount++;
      }
      GivePlayerMoney(random(PCount), 3000);
}

Or like the guy over this post, who was faster xD ^^
