The game won't allow me to sim through free agency. I tried to sim one day and the game stayed on an infinite loading screen and simming thru the entire free agency doesn't work either.

If you would use the support form (go to our main page and click support) and look under HELP to find the instructions to submit your game files I will take a look and see what is holding it up

I've submitted the file

I just figured out this happens when I allow the CPU to control offseason tasks during free agency.
