Description:
Railcraft (in quite buggy beta) doesn't allow removing specific items. Thankfully removing entire pools is doable

Steps to reproduce:

Version Info (Exact versions only):

@ElectroBot I suggest just blanking out railcraft loot tables. Does that work?

Yes. As I mentioned clearing the Railcraft loot table pool does work. Clearing the whole loot table would clear all the loot from all mods and vanilla.

I mean like blanking out the loot table railcraft:chests/simple_dungeon instead of the vanilla one. Eh, how else can I explain to you... Who told you to blank out the one with minecraft namespace...

[17:32:06] [Client thread/INFO] [minecraft/GuiNewChat]: [CHAT] ERROR: No loot table with name railcraft:chests/simple_dungeon exists!

When I run /mt loottables all, then only railcraft table (not pool) is railcraft\chests\village_workshop.json

@ElectroBot You can close this issue now. I got a bugfix for this in railcraft. After that bugfix, loottweaker will be able to handle railcraft tables properly.
