My younger brother has tempered with the files, installing mods and etc without my permission whatsoever.
Now after deleting all of them, I am seeing older players such as Lewondowski, Messi, Neymar and hundreds other with ages of 19,21 and so on. This has created a massive mess in the entire game, and with me playing career most of the time, you know how chaotic it is.
I tried Verifying integrity of game files quite a few times, deleted all his mods but to no avail.
I seriously need you guys' advise on how to fix this mess...
