Im unable to set its fluid and it does not auto selects it as well anymore.

If your save is form game version 2.0, please run the code:
/c local gui_list = {"force_datas_main", "restore_button", "set-linked-container-password", "linked_chest_signal_frame", "buffer_chest_frame", "proxy_chest_frame", "set-linked-pipe-password", "link_pipe_fluidbox_capacity"} for , player in pairs(game.players) do for , name in ipairs(gui_list) do if player.gui.relative[name] and player.gui.relative[name].valid then player.gui.relative[name].destroy() end end end

If not working, please open a new game, check.

Playing 2.1.
Cannot execute command, <name> expected near ","
Need _before , in for statement.

That does the trick, thank you.
