CHANCE on loottables may not be calculated correctly

[joligario]

Formula behind the scenes doesn't make any sense.

    $total = (($chance/100) * ($lootdrop['probability']/100)) * 100;
    $chance_total += $chance;
    if($lootdrop['probability'] == 0)
      $chance = 0;
    if($lootdrop['probability'] > 0 && $lootdrop['probability'] < 100)
      $chance = $total;
    if($lootdrop['probability'] >= 100)
      $chance = $chance;

$chance_total not used, of course $chance = $chance, etc.
