I already have a multi tool that works as shovel, axe, pickaxe, and sword. The pickaxe and axe works perfectly fine. When using the axe feature of it it only breaks planks and logs and no modded wooden items. When using the sword part of it it kills perfectly fine but it doesnt give any mob drops, it only gives mob drops from modded mobs.

What do you mean it doesnt give any mob drops?

When I kill a mob it doesn't drop anything.

That is weird how many times have you tried? Is it possible that you got unlucky?

I tried many times for all mobs but when I attack a modded mob I get drops on the first time.

By chance are you messing with mob drops in anyway? Are you using any other mods?

I am not messing with mob drops and I am using other mods but when I use a normal sword I get mob drops.

Did it do that in your dev environment?
