If anyone knows how to remove it from getting carpentry XP please let me know. For now it just too good of a recipe in the game to remove. From what I've been able to tell digging into recipe files and how the game handles them, remove the 'category' line under the recipe. It reads Category:Carpentry, right now. Without a category line it doesn't register to add XP as if you'd used a skill related recipe. Treats it as generic, like taking a battery out of a flashlight. Edit: I checked the log stacking recipes, and those do list carpentry in their entries, so I'm not sure why those don't grant carpentry XP but the lumber stacking does. I tested it out by removing the Category:carpentry entry and it still granted experience, so I'm way off Edit 2: Found it... these lines are commented out, but it must be implemented somewhere else. In the XP system from crafting, anything that involves planks grants woodworking XPs: This was under ProjectZomboid\media\lua\server\XpSystem\XpUpdate.lua --~ if resultItem:getType():contains("Plank") then--~ getPlayer():getXp():AddXP(Perks.Woodwork, 3);--~ end--~ if item:getType():contains("Plank") then--~ getPlayer():getXp():AddXP(Perks.Woodwork, 3);--~ end So... anyway, I don't know how to bypass that yet... but it's a start
