ive had a finished 260,000 stadium since level 15, i have 3.97M fans , (as a marker jose mourino only has 3.4M) we are now level 19 but i was getting a full 5% charging 55$ in levels 16,17 & 18, Now ive had to lower to 50$ and im still not getting 5% all of the time therefore in my opinion tweaks or changes have been made???
