"This is your main squad, the club has 22 players eager to show you their capabilities. Current squad size limit is 27 players, limited by the stadium Dressing Room level of 1". And I have three youths. 22 + 3 = 25, so why cannot I buy more players? You are more intelligent so explain why i have error that avoid me to buy more players.

No bug here, you were trying to buy another youth and your youth limit at lvl 1 is 3 players. That s why you get the error!

Wow, you like pointing fingers. Try pointing at a mirror.
