AI minimumn fee release clauses

They don't seem to change when a player signs a new contract, even if they are top players they don't increase accordingly.

One example in my game is the new world player of the year; Alvaro Guerra (newgen). Had a £15,000,000 minimumn fee release clause before winning player of the year, 5 days later signs a new 4 year deal with a minimumn fee release clause of £15,000,000.

This makes the game unrealistic and very easy to sign the top players, if they are based in spain and therefore must have a min fee release clause.

Is this a bug?

very next game day.

i gave this player this min fee release when i was managing real madrid, hes since improved a lot since the youngster i had, yet min fee remains the same, despite signing two new contracts.
