Hi Manu,
Today I noticed a game changing bug. I played a game in Text based mode and changed the player style from his usual 'power baseliner' to ' Volleyer' for the match. After the match had finished and I returned to the training screen, I noticed that his playing style had changed permanently from 'power baseliner' to 'Volleyer'. I'm not sure if it will change back if I attempt to play a text based match again and change his playing style back to a Power baseliner but I usually watch matches in 3D. I will play a text based match later and see if I can change his style back to what it was.
