First of all, there will be a limit formations, there are only 1000 of them.
Then the players, their 32,000 or 35,000 as much as possible. CM adds them without limit. At least a million))) BUT! After the limit, the names disappear in the game (including on T-shirts)
About the league...
Stated that : For CM 16 the expansion of the database allows to have up to 2048 formations (instead of 1000) and up to 65536 player names (instead of 32000).
And how to create over 1000 formations? Please Help!!
