In single player, I can craft the draconic chestplate perfectly fine in the fusion crafting. On my private server it wont craft, even if I set everything up in creative and spawn the correct parts in. The "START: button in fusion crafting appears but nothing happens when you click it.

Current Behavior

Fusion crafting shows START button for draconic chestplate but clicking it doesnt do anything on a server.

Steps to Reproduce

1. Set up draconic evolution fusion crafting
2. Place items for draconic chestplate in crafter
3. Click START
4. Nothing happens

I can confirm.
In the server files of the latest and final version 2.0.0 of ATM3R the custom fusion recipes are missing.
Workaround: Copy the fusion recipe file like mentioned by @klAvAx

Same here. Also ATM Tweaks Growth essense.

Looks like i found a fix.
Copy "CustomFusionRecipes.json" File
From singleplayer "config\brandon3055" client
To multiplayer "config\brandon3055" server
Then Restart the server & most likely enjoy the fix

P.S. i used a non-upgraded wyvern chestplate, and it started crafting after hitting start
i believe @CrankySupertoon should test this and update the server files

i encountered this issue too
fixed it by simply removing the angel ring from the recipe ...
it can still be crafted by the original recipe.
