Hello, I'm gonna guide you into fixing the mod to a playable state in which you can draw, and build structures, you will however be unable to sketch anything but fire, axe, and pickaxe without cheating, currently I haven't figured out a way to enable the prototyping without being unable to build structures

Fixed it!

Due to the way default has asked, I can't just upload a fix because they will flag and report it.

Lets get started, you only need to edit two files

Make a copy of these both in case something goes wrong, or Default updates it.

• First we'll navigate to where the mod actually is : Which by default is here "C:\Program Files (x86)\Steam\steamapps\workshop\content\322330\2345989057
  
  
• Next we'll open modmain.lua preferably with notepad++, We'll be going to line 278, for anyone else searching for "RABBIT_DRAWING_ONE" will be just fine
  
  https://gyazo.com/c16bc5dcae8eedf555c85aea28be5ac2
  
  
• Now you see where is says "tech = "RABBIT_DRAWING_ONE"', the one above it says NONE, so change all the tech's to be the same as the campfire, axe, and pickaxe.
  
  
• Click file > Save, next we'll go into the Scripts folder, then into util and open "drawing_prototyper.lua"
  
  
• Again we'll be going down some lines, but ill make pictures for you instead

Search for "AddComponentPostInit("builder", function(self)" or go to the line number listed,

Right where it says "Local _KR" Start highlighting, we will be highlighting pretty far, so bear with me.

Scroll all the way down to line 930 right where it says "_ETT(self)" delete all of it.

Scrolling down a little bit will lead us here, you need to delete THAT end specifically.

This part is right after the 'end' we just did, you need to highlight "b_rep2.KnowsRecipe = function(self, recipename)" and move down till the very last end of that block, which is 6 total,

But basically it says "return false" and then end, and you need to highlight to there, and delete it all.

Congrats, the mod will now work for you!
If it's too much work for you, ill host it privately and you can add me and ask for a link.
