The TC guidebook, "Materials and You" is (in the current build) not behaving like a book. I can not place it in an Akashic Tome, nor in a modded bookshelf (The mod Builders Additions provides a bookshelf that contains an inventory like Bibliocraft did before it).

Minecraft: 1.16.5
Forge: 36.1.4
Mantle: 1.6.92
Tinkers Construct: 3.0.3.111

Confirm below that this issue is not covered on the roadmap or "What's New?"
Didnt see this specific problem, but I understand this is an Alpha so this may simply not be done yet.

Can it be reproduced with just Tinkers Construct? If not, list the other mods required to reproduce the issue.
See notes above inre: Akashic Tome and Builder's Additions.

Closing as a bug in other mods, if anyone has this issue yell at the offending mod for reading registry names instead of using tags

I have tagged all my books under the item tag forge:books/guide and forge:books. Suggest to the other mods they should be using a tag check instead of a registry ID string match, way too many false positives in experience with registry ID check
