We've just released hotfix 18.3.3 for Football Manager 2018.
Again this hotfix is to address some stability issues we've been made aware of since the release of our most recent update. As always is save game compatible allowing you to continue your current save game.
Once you open Steam the game will automatically begin to update. If FM is already open, we recommend first of all saving the game then exiting. Once you've done so the game should update, but if you find it doesn't just restart Steam.
If you encounter any issues or problems do please take the time to raise them on the SI Community Forums Bugs Forum.
