Forge v36.1.32
Twilight Forest v4.0.490

Steps to reproduce:

1. Check forge tags: https://github.com/MinecraftForge/MinecraftForge/blob/1.16.x/src/generated/resources/data/forge/tags/items/feathers.json

What I expected to happen:

• Raven feathers should be using the official forge tag forge:feathers.

What happened instead:

• Raven feathers use the forge:feather tag instead. (It is not plural)

alright, I updated those as well as the ores and gems tags

Mangrove Wood is also missing the minecraft:logs block and item tag.

fixed these and also went through real quick to make sure there werent any other weird ones. If you find any more please let me know. Thanks for your help!

Yeah, np!
I think the only other thing to mention is that the ingots and metal blocks aren't using the forge:ingots & forge:ingots/ingot_type and forge:storage_blocks & forge:storage_blocks/type block and item tags.
