Is there any way to manipulate all loot tables at once ?
For example i want to remove all minecraft:iron_sword from all loot tables. Would i need to call every getTable for every table and remove it one by one or can i somehow use getTable or so to get all tables in a single object ?

I've actually been working on a feature to allow for this, since about a week ago. Unfortunately it's run into technical difficulties, and I haven't yet figured out how to get round them.

Np ;) In the meantime i used "LootTableTweaker" to do this. Not the optimal solution having 2 mods alter loot tables, but at least seems to work ;)
