Hi Graham,
Tomasz Janeczko cleared this issue up for me, and I'm glad there is
not bug, and it was my misunderstanding about AFL instead.
Graham you mentioned that I could easily just explore for the
results instead of using debug? Sounds good, but I'm not sure how to
do that. I'll see if the manual explains this. I'll also take a look
around in the program for this.
