CK 1. I now I to use it to advance the story so obviously it's not happening right nowCK1 or CK2? game part? if you make a statement it is difficult to find a solution. Maybe the error is with Jenny or with Aubrey's sister or maybe it is when loading a save data from CK1 to CK2 and you can't answer Clhoe.
In general, I always recommend not to disable the rollback mode to avoid these errors, if later you know the game and want to play without cheating then disable the rollback mode
