Modpack version:
2.3.1.

Description:
Made an Atomic Disassembler, tried to break an empowerer from Actually Additions, it deleted the item. I tried to break wood & dirt and it gave me the drops from those blocks. I tried to break stone afterwards, it deleted the stone. Then I made a furnace, I broke it, it destroyed the drop.

Steps to reproduce:

1. Make the item
2. Try to mine anything that requires a pickaxe
3. It destroys the drop.

Expected behavior:
It should act as a normal pickaxe and mine the stone, not destroy it.

Edit: Is it really efficiency 20? Cause it doesn't break stone instantly. A speed increase should also be added. I'm using fastest option and it's quite slow... It breaks dirt instantly at least.

That's apparently just how to Atomic Disassembler works. There are no configs to change the block destroying behaviour. (It makes sense looking at its name.)

There are 5 modes for it, you'll need to toggle between these for a faster mining speed: https://wiki.aidancbrady.com/wiki/Atomic_Disassembler

Actually, all I can think of is changing this in config/tool_progression/tool_overwrites.cfg:

S:"mekanism:atomicdisassembler"=pickaxe=4
S:"mekanism:atomicdisassembler"=shovel=4
S:"mekanism:atomicdisassembler"=axe=4

to

S:"mekanism:atomicdisassembler"=pickaxe=4,shovel=4,axe=4

It shouldn't destroy the blocks

Well, there are no configs for that.

changing to
S:"mekanism:atomicdisassembler"=pickaxe=4,shovel=4,axe=4
fixes the issue

Also breaks dirt instantly on normal(20) and stone instantly in fast mode(128)

Implemented the change in 2.4.0 (https://www.curseforge.com/minecraft/modpacks/divine-journey-2/files/3464189), which should fix this issue.
