I may be wrong but I think possibly the mistake you are making is training like Paco - High volume (like most pro's do)
I think that is too much if you are drug free.You stay fuller (spare glycolgen) if you train with less sets. use the cardio and diet to burn fat off..If I were you I'd try Max Ot - very good program for drug free guys - short and intense (40 minutes).
I understan you a lot.
Paco noticed about it and before 2nd show, he cut out the set and he prohibit me to train failure.
I think maybe,all the natural bber should stay lean(enough to do the guest apperance) before start preparing for the show.
If not, our muscle cant resist the severe diet and end up looking dead and smooth.
So, We decideded that I keep on staying around 80kg always.
Hopefuly I can show up on stage hard like you next time.
