When I use IndustrialForegoing's Item Transporter (with the Efficiency Addon ,whitelist and Regulate Mode) to transfer items from a SophisticatedStorage container to a Powah's Energizing Orb, the items are duped. When I switch to the vanilla chest, or remove the Efficiency Addon, or replace the Energizing Orb, everything runs fine without issues. I don't know which mod this problem is caused by, so I have to choose one to create an issue.

Here is a video describing how the issue happened.

What mc version are you on?

and based on what I am seeing in video this seems to look like IF or powah bug - when you setup transporter to pull clock from the empty energizing orb and things are being inserted into chest out of thin air - I can't imagine how this could be storage bug where it would itself be inserting stacks into itself or somehow telling transporter that the orb has items to pull. But I will take a look once I know what version I am working with.

mc 1.21.1 with neoforge 21.1.200

mod version:
sophisticatedcore-1.21.1-1.3.62.1074
sophisticatedstorage-1.21.1-1.4.47.1223
industrialforegoing-1.21-3.6.34
Powah-6.2.6

I was able to recreate the same with functional storage drawer so please report likely to IF because this appears to be an issue in item transporter code.
