Modpack: BoxyWorld 1.2.2
Version MC: 1.14.4
Mod Version: 14.8.6
Forge Version: 28.1.90

Problem: I can craft wood tanks, but that is it. Although the other recipes show (1 tank in each corner of a crafting table) the end product is not obtainable.

Replicate problem: Join server (if you wish) and try to craft any tank higher than a wooden tank.

Thank you!

Try recipes on this page.
It seems my mod failed to load item tags. I'll update my development environment and work for this issue.

Thank you! I will try when I get home tonight from work... Ill update when I do.

So, It doesnt work with those recipes either. But Im guessing that is suspected.

I installed BoxyWorld 1.2.3, the latest on 2019/11/25, but tanks can be crafted.

In that environment, tag forge:stone refers to these items.

forge:stone : 17 : explorercraft:slate, explorercraft:marble_polished, minecraft:infested_stone, minecraft:polished_andesite, explorercraft:slate_polished, bluepower:marble, explorercraft:marble, explorercraft:basalt, explorercraft:basalt_polished, minecraft:granite, minecraft:polished_diorite, minecraft:diorite, forbidden_arcanus:dark_stone, bluepower:basalt, minecraft:polished_granite, minecraft:andesite, minecraft:stone

Do you have ways to know which blocks/items are registered as forge:block tag?
If yes, please show me.

Edit: I tried in single player world. I think you're in multi player server world. The server might have data packs to modify tags.

So I have to apologize, you are correct. The recipes you sent me do infact work, the reason they didn't was my fault and human error.

So Ive come to the conclusion that JEI shows the wrong recipe as you stated previously, and the recipes you sent do work. I really appreciate it! Sorry about the last confusion, I feel bad.
