As the title says, when I update any mod and load a world any ship with cargo bay circuit connections removed suddenly regains them.

Interesting. I thought of the network on the cargo bays as an extension of the hub. In your case you removed some wires manually and then they get added again, as you change what mods you use? Guess that's the migration script, which adds the circuit ports and wires, when it gets added to a new or existing game. Will have a look at it, if I can make that configurable.

I changed it, so it should no longer create a circuit connection between existing hubs when chaning the mod configuration.

Thank you very much!
