im playing version 1.12 and i cant craft them is this an issue or can it not be done in this version?

got a log ? maybe the recipe json is not being read?

{
"type": "minecraft:crafting_shaped",
"group": "subaraki",
"pattern": [
"GGG",
"EEE",
"ICI"
],
"key": {
"G": { "item": "minecraft:glass" },
"E": { "item": "minecraft:ender_pearl" },
"I": { "item": "minecraft:iron_ingot" },
"C": { "item": "minecraft:compass" }
},
"result": {
"item": "telepads:telepad"
}
}

the recipe states here that it is crafted with ingots.

updated the wiki with a warning under the crafting recipe.
you can alter the recipe json if you want to, opening the jar file with your favourite zip program
