Hey Cristian,
Thanks for taking time to send out the diff. I thought this would be
enough but there will still be a disconnect between opp_count and idx
of the opp we populate. Consider a case were we get to have a valid
opp just after duplicate opp. The opp_count will still limit us on what
levels we are allowed to see.
