Basic Structure recipes return Null items on servers.

[Brian-Wuest]

In 1.12 the recipes for the Basic Structure return Null names instead of their proper names. This only happens for servers and not for single player.

[Brian-Wuest]

This was fixed with version 1.3.0.6.

[Ramzah]

I'm on version 1.3.0.7 and this bug came out again but on structures like Mineshaft entranc,e, Barn, etc.. Only on server, single player works fine.

[Brian-Wuest]

I am running the latest version and confirmed that the recipes are working properly on a server.

Please make sure that your server configuration options allow these items to be crafted. Server settings override client settings.

Can you show a screen shot of what you are seeing on a server. I will also need to see your server configuration file and what version of forge you are running.

[Ramzah]

Server configs allow items to be crafted. (Everything set to TRUE except loft house) Forge version: 14.22.0.2452 By server configurations i guess you need the server.properties file? Here it is:

[Brian-Wuest]

I meant the Prefab.cfg from the server. Servers have their own configuration file that is used instead.

I see you have JEI installed. Did you get the item through JEI or the Creative Menu or through the Crafting Table?

[Ramzah]

Here's the prefab.cfg from the server:

I tried both, via crafting and creative menu, when all failed i even tried /give prefab: but the item won't even show up in the suggestions in the chat when i press tab. I didn't try from JEI honestly, i only use it to check recipes.

[Brian-Wuest]

Thank you for the information. I was able to duplicate this.

🤕

I thought I fixed this.

Re-opening issue.

[Ramzah]

Aww that's too bad. If it helps i can add something i noticed: In the creative menu the item appears to be the correct one, it only gets "corrupted to NULL" once you let go of the left mouse button to either add it to your inventory or drop it on the ground (you can tell if you drop it on the ground by the item sprite turning green) If you try using that NULL item the GUI is offcentered and if you click on preview the game crashes. (if you click on build nothing happens)

[Brian-Wuest]

Yeah, the issue is because the Basic Structures use NBT data for the data to show in the GUI and in 1.12 they changed things which broke things.

[Brian-Wuest]

You should be able to use the crafting table. That works without issue. I confirmed this by crafting a Barn item.

The only problem seems to come from getting the items from the Creative menu.

[Brian-Wuest]

I was able to figure this out last night. I pushed an updated version to curse forge and it should be approved soon. Closing this issue.

Thanks!
