Ok. I think I understood now...You can gain enthusiasm during Friday's semi-finals by playing PO-Normal if you have less than 15 level, but if you have 15+ playing PO-Normal has no sense, because your enthusiasm can't be higher. So in result in this particular case you have no posibility to even maintain an advantage built before. VERY VERY stupid...but ok. I apologize for imply a bug and confusion. My big and sincere congratulations for Italy!
