Hi, same thing for me. Cannot progress when a loan or sale offer has been made. FC United career, problem seems to have started in 2029. iOS 11.2.1.
Here is an example where I have accepted the offer but the option to continue is greyed out and the compulsory action button is still active. (1st screenshot)
The only workaround to progress that I’ve found is to change the transfer status of the affected player (when not listed, change them to listed and then change them back to not listed again). (2nd screenshot). But this means you can’t sell or loan anyone.
And when clicking continue, the problem returns for other players when any loan or sale offer comes through.
Will send save
