The fully grown clusters (Diamond, Emerald, and Quartz) arent dropping any resources, in the version included with Better Minecraft Fabric 1.19.2

Nevermind, i found the reason, the Soul Steel pickaxe (for some reason) doesnt drop the resources, but vanilla pickaxes do :\

I don't know what the mod that adds the Soul Steel pickaxe is but my guess is they forgot to add their pickaxe to the item tag #minecraft:cluster_max_harvestables.
