im playing with Blueprint Sandboxes mod and when i enter sandbox mod my linked chests and pipes have another storage.
i think when i enter sandbox, mod switch faction channel.
is it possible to add function to chose faction channel in Linked Chest And Linked Pipe GUI?

This feature is not necessary, And this will lead to many unnecessary problems.
"i think when i enter sandbox, mod switch faction channel." Isn't this just right?

If you don't want to do it, you can switch channels through commands:
/c game.player.force = you channel
