Last year I was 4 blueprints away from having them all after 3,200 hours playing the game.
This year I found some thinking I got them all finally but when I looked at grim tools it said 15 more.
You must have added more at some point?
I am currently over 4,000 hours and still at 15 blueprints.
I know you added the roll three times on blueprints for chests, but can you make it so that the third roll if already known gets removed from the list of possibilities? This way I am for sure to get them at some point.
it already rerolls more than 3x
