I try to create a custom crafting table that has a grid of 4 by 4, so I first tried to create a recipe that extends ShapedRecipe, call the super in the constructor and then call SetCraftingSize(4, 4) as mentionned in the ShapedRecipe class. However, it seems not to work, I took a closer look to the vanilla class but I don’t really understand why they are using CraftingInventory, And CraftingContainers. So I tried to « rebuild » it with IInventory. It perfectly works on singleplayer but I have this weird error when trying to connect to a server « UTF-8FormatException : Malformed input around byte », and an error on the client only, I guess it’s an error of networking but I don’t really know :

See error

 

And here is my Recipe Class :

See class

 

thanks for your help if I can have any !
