Well, I haven't read all of your code, so I can't say authoritatively that I know exactly what the bug is, but i have read the good_ones_go funtion, and fortunately your program is nice and moduler, and your variables names are fairly clear, (the only thing i needed to look up anywhere else in the script is what "@good_ones" contains, and what you pass to "good_ones_go" when you call it) so I think I have a pretty good idea what's going wrong.

Rather then just fixing it for you, let me ask you a question, what happens if you run this script.... 

# perl
use warnings;
use strict;
my @good_ones = (100..110);
foreach (0..$#good_ones) {
   print "$_: $good_ones[$_] ...";
   if (rand() < 0.5) {
       splice @good_ones,$_,1;
   }
   print "($#good_ones)\n";
}

(PS: you may be tempted to "fix" your script by adding a single call to "last;" ... I wouldn't recommend that. Consider what would happen if the camel moves one pixel, and that puts him close enough to pick up two monks.)
