Describe the bug

When the world is reloaded, the assembly controller and tube will "Break", this has 2 effects;

1. The tube next to the assembly controller, even if looped, will start leaking air and play the depressurization sound effect, but give no visual effect. It will keep leaking air until individually replaced
2. The assembly controller will not work until replaced.
   This effect might be because of a chunk boundary error, because of this I have attached a screenshot

Note that in this image I have the pipe looped but before I did not

Definitely looks like a chunk boundary problem Placing the loop like this and reloading the world breaks the loop in half, moving the loop 1 to the right still causes effect on the pipe connected to assembly controller.

For the final test, I moved the entire thing one block to the right.

The pipe in the bottom left right next to the chunk boundary will cause effect 1, and the assembly controller will also "break" again(? untested because i'm dumb and swapped the IO, but assumptions are

1. On world reload the assembly controller tile entity "breaks"
2. The assembly controller forms a "bugged" pressure network
3. This "bugged network" stops attempting to form a network or encounters an internal error that stops it from doing so on hitting the nearest chunk boundary)

How to reproduce the bug

1. Place assembly controller and hook pipe on it
2. Unload world
3. reload world
4. assembly controller and pipe breaks

Edit 2: This effect seems to be unrelated to the assembly itself. It just doesn't want to connect across the chunk boundary.

Expected behavior

Assembly controller and pipe continues to function

Additional details

This effect will ONLY happen on world reload. This does not happen on dimensional load. Area is not chunkloaded. This effect will still happen if world is loaded in another dimension and goes home.

Sounds like the same issue as #1371 and one that I have never been able to reproduce. I tried building your example above in a dev world (as well as on a test dedicated server), and it all works for me.

Hi desht, thank you for your response. I will attach my world file and maybe that'll help you out.
This is a FTB Evolution world tested on modpack version 1.20.0. This will be the Google Drive link shared. Also shared is my latest.log in which this bug has most likely occured.

I will be out for a couple of days so I am unable to help you troubleshoot the issue further, but I suggest looking at maybe the region of the problem chunks and seeing if they're different. Idk, just a shot in the dark.
