I'll explain the problem using the picture below.

As shown in the picture, I'm trying to push an item from the ME interface on the left side in to the ME interface with a storage bus attached to it.

This is the item in the ME interface(Input)

The setting on the Storage Bus.

As we know, the item should land on the ME interface with the storage bus attached to it. But, in this case, no.

When I replace the ME interface with a chest, the items do land on the chest.

It is also bugged when I try using it as a sub-network. Items wont be able to transfer into the sub-network or transfer out of the sub-network when a storage bus is attached onto a ME interface.

the ME interface on the left side makes no sense, or is there another storage bus attached behind we yet do not see on the screenshot!?

Skip to Edit: due to blindness

if YES there is another storage bus, then the power bypass ther makes no sense, it is connected to an ME interface with no power connection (the left one, because the storage bus transmist no power) and on the other end the bypass is connecte to the cable with the same Interface it already is connected with ... there is no power by any means ...

EDIT: my fault i have overseen the fiber cable disconnecting the left interface from the whole network ... derp ...

an ME Interface has special Code when connected to a Storage Bus, i think this is impossible due to the fact that you can access the whole ME Storage behind an Interface when Facing it with a Storage Bus

I've tried to transfer item from a storage bus into a ME interface before and it worked. But for some reason, that method stops working.

Besides, sub-network seems also is broken.

This is my sub-network feeding into a auto-sieving set-up. It's a replicate of what Soaryn did on his stream on FTB infinity skyblock.

Setting on the ME interface linked to the main network.

Setting on the Storage Bus connected on the ME interface.

Setting on the sub-network interface.

As you could see, items can't be transferred from the main network in to the sub-network. It should be able to as seen on Soaryn's stream.

1. If you have a security station, remove it or put a blank biometric card with all permissions given into it (This is most likely what makes you think that subnets are broken)
2. Does it work if you filter the storage bus and assign it a higher priority?

Ahh thx for the help there. It works.
