Available on PC since March 11, Rise of the Ronin has been plagued by several technical issues. Some users have even reported having their saved data deleted.
According to several threads, save files can disappear after 5, 10, or even 15 hours of gameplay. Note that there is no solution or fix available at this time.
On X, Team Ninja announced that they have launched an investigation into this very problematic bug.
