Hoping to finally get help from anybody, I´m reposting my problem with fm2016:
" As I´m ready to register my team for the European Champions Cup, suddenly all of my first team players that are at the club (not the ones loaned out) are gone! The images show that I have not excluded any of them through the filters. I already tried to go on holiday, hoping that this would fix the problem. It didn´t: the assistant coach just promoted 2nd team and youth players to the first team and registered them for the competition. Neither updates nor taking a longer break from playing solved the problem. Also just normally looking at my squad (without the registration tab) all of the first team players seem to be gone... "
Since September I haven´t received any help yet. Please help me now! Thanks!
