This is a Workaround Fix for the (old but temporary fixed and now back again) Bug where the progress of a written book will be lost when traveling. This Fix adds a backup of the progress to your own Sim and adds it back to the written Book when resuming. So this Fix will only work well if you write one Book after another.If you write several Books at the same time, the progress from one Book might be added to another, so keep that in mind. You also need to cancel the writing before saving & closing the Game. This Fix does not override any ingame ressources so it is compatible with my Slower Writing Mod.
