Annoyed that you can’t toggle Fast Crafting for your old saves? If you’re comfortable using a hex editor then I’ve got the solution for you!
 
 

Instructions

I noticed some not so helpful Reddit posts alluding to being able to insert what Fast Crafting enabled adds into a save file after creating it. After spending a few hours I’ve been able to replicate this repeatedly in my own save files and new ones that I have created. No idea if this will carry forward with patches though. The instructions are pretty simple but you do need to know how to edit your save file via some sort of hex editor. I personally use Notepad++ with the HEX-Editor plugin but feel free to use what you like.
 
 
Warning: Make sure you create a backup of your .sav file prior to trying this out!
 
 
Insert the following hex values immediately before the ’00 11 00 00 00′ preceding the XPGainMultiplier entry (search for string value to find it as it only exists in a single place)-
 
 
0d 00 00 00 46 61 73 74 43 72 61 66 74 69 6e 67 00 0d 00 00 00 42 6f 6f 6c 50 72 6f 70 65 72 74 79 00 00 00 00 00 00 00 00 00 01
 
 
So for example my save file in this location looks like this-
 
 
50 6c 61 6e 6b 00 0d 00 00 00 46 61 73 74 43 72 61 66 74 69 6e 67 00 0d 00 00 00 42 6f 6f 6c 50 72 6f 70 65 72 74 79 00 00 00 00 00 00 00 00 00 01 00 11 00 00 00 58 50 47 61 69 6e 4d 75 6c 74 69 70 6c 69 65 72
