3. Fill the pressure chamber with air (at almost 5 bar)
4. Brake one pressure chamber bloc and replace it

The pressure chamber should not explode

Actual Behavior

The pressure chamber explode

Any other comments?

First seen on a dedicated server with a large modpack. But able to reproduce in single player with only pneumaticraft.
This is NOT #874.

Yep, there is a problem here. The multiblock break/reform logic gets really messy once both volume upgrades and base volume calculations due to multiblock size come into play. I'll take another look at this and see if there's a cleaner way to handle it.

In the video for #915 I also make a demo for this bug https://www.youtube.com/watch?v=_QjUQIeenKs&t=0s

Can you try build 275 from https://jenkins.k-4u.nl/job/PneumaticCraft-Repressurized-1.16/ ? Hopefully it fixes the problem you're seeing.

It works in singleplayer with the full modpack. For multiplayer test I need to wait the next server update.

So I think we can close this issue. (I'll re-open if the issue still happen on the server)
