Bug description
As the title says if you connect 1 pipe to 2 sources it will not extract gas from all sources even when the first source is empty

Steps to reproduce the issue

1. Place 2 Electrolytic Separator on either side of a pipe
2. Connect the pipes to the 2 machines and use wrench to make them extract from them (Be sure the machines are set to output gas to the side you connected to the pipe)
3. Turn on machines

Expected behavior
All sources should be able to provide pipes with gas

Log files
No logs since its not a crash

Versions

• Minecraft version: 1.20.1
• Forge version: 1.20.1-47-1-43
• Mod version: 1.1.4
• Mekanism: Mekanism-1.20.1-10.3.9.homebaked-all

Screenshots (Optional)

Did you connect the pipe to a destination?

Yes their connected to 3 mekanism infusers

Did you connect the pipe to a destination?

You are using 1.20.1. Mekanism is not yet officially released for that version.

This happens with or without upgrades installed in extracting side

Heres proof:

@henkelmax i have just found that this also happens with Item pipes, and normal vanilla chests, so its not mekanism related

Did you set any filters or destinations?

Did you set any filters or destinations?

Nope in the screen shots its litterally just extract pipes with no upgrades and no nothing, and even if i add upgrades it does not work

Not sure if you understand how the mod works, but there are a lot more inserting connections. The mod chooses the shortest path by default.

Ok, now I understand the issue, thank you for providing a simple example!

I know how it works, but even where it moves the items to which is the shortes it never pulls from the right chest. here let me make a completely cardboard cut version so you can see what the problem is:

A and B are chests filled with items
C is the out put chest

When setting this style of "2 source connections pipe" up the pipe will NEVER pull any items or gas (after pipe type and machine) even when 1 of the chests/machines are empty, it seems that the first "side" you change to extract is the side that actually works, and the secound 3 or 4 connection set to extract never extracts from the chest or machine, you need to disconnect the side you connected first and reconnect the side which was set to extract after the first one.

Note: i have found that doing this with item pipes seem to work some times but not all, seems to happend randomly and not depend on oriantation, though when doing it with gas pipes (which you say are for mekanism) it never works and will always only extract from 1 machine
