Pipes lose pressure on load when they cross chunk border

[Hiranus]

Describe the bug

When loading game pipes "break" and lose pressure. Its like they dont see that there is a pipe right next to them, just in different chunk. To fix this I have to break all the pipes that cross chunk borders and replace them.

Here's a video showing the issue. I loaded the game and had to replace pipes because they were leaking pressure (notice that hissing sound). The game was saved with ~3.25 bar in the system.

How to reproduce the bug

Build something simple that crosses the chunk border, save and load the game, and try to pressurize the system.

Expected behavior

Pressure is kept in the system after reload, even if some pipes in network are in chunk that is not loaded.

Additional details

I play ATM10 pack, version 1.7a

Which Minecraft version are you using?

I'm afraid I can't reproduce this. I did the following:

• Create a tube network crossing a chunk boundary
• Put a creative compressor (0 bar) on one end, verified all tubes are at 0 bar
• Quit world, log back in
• Raise creative compressor to >0 bar
• Observed all tubes pressurized, no leaks

Not sure what's happening in your world that isn't in mine. I've also tried various combinations of forceloading one side of the network and not the other, teleporting away and back, switching dimension etc., and I haven't seen any leaks along chunk boundaries at all.

Maybe there's something in ATM10 that causing problems (don't know what "optimisation" mods are in that pack, but they're a good place to start looking).

Seems like Connectivity causes this.

Having the same issue here, pipes get disconnected at chunk borders.

Running the mod on a server with the Craftoria modpack, (pack version 1.5.0, mod version 8.1.4)
Issue happens when the server is restarted.

@LyraGhost can you try without the Connectivity mod? Would be good to get corroboration on that one.

I don't see that mod in my mods list

I think I'm having the same issue. Whenever the server restarts and I enter my PC:RP area, I hear hissing and have to break and replace the noisy pipes to fix pressure loss. They still render as connected, but leak pressure and make noise.
