Describe the bug
When inserting items with external mods pipes the item isn't extracted from the inventory.

Mod used: Refined Pipes.

To Reproduce
Steps to reproduce the behavior:

1. Place Barrel
2. Place a item pipe beside the barrel
3. Place a chest beside the pipe.
4. Then when the barrel is filling nothing is getting extracted from the inventory that the pipe is connected to.

Expected behavior
idk probably the item shouldn't be in the inventory

Screenshots
Setup:

Version
Minecraft Version: 1.16.5
Forge Version: 36.0.42
Ex Nihilo: Sequentia Version: 1.16-2.0.1.0
Refined Pipes Version: 0.5

i think it is fixed with the newest version, can you try it with version 2.0.2.1?

actually, i have recreated your example, it extracts the dirt well, BUT the saplings arent pulled out of the chest if there are more than one sapling.
(tested with Exnihilo 2.0.2.1 and Refined Pipes 0.5 on Minecraft 1.16.5)
But i think thats a bug from refined pipes

yeah, something is acting weird.

still acting the same in 2.0.2.3
so it maybe is the refined pipes.

it is definitly refined pipes, i dont know whats causing it, but i think it just looks for storage with more than one space

yeah, because the pipe is responsible for the extraction and inserting. the barrel only has the inventory.
and if you use hoppers it works fine.
