ActuallyAdditions#324
looting AA's compost deletes the currently selected item and places a torch when the item is eligible to do so and the torch is taken from the hotbar.

edit: also happens when the torch can't be placed in that location

Yea, I have no idea why this happens so I'm just going to hope that it's your problem @blay09 :P

I assume this was fixed on Actually Additions' side. Client Tweaks is just simulating a right-click with the torch, it has no way of deleting items as it's client-side-only.
