I have a compact circuit which shows 2 sets of signals and as I tried to configure a third, it just does not show up. Works inside when I configure it as internal and disable packed mode but when I change these both settings nothing show up on Nauvis.

Here is the export of the circuit: https://factoriobin.com/post/in_NfFl_fjNjS-UY-EXPIRES

I try your setup and it seems to work properly:

You are right, I found the issue! As soon as I power the compactcircuit the blue window pops up. It is as the other previous combinators had already power somehow but the additional combinators for the blue window had never seen power and therefore did not work.

Maybe I used picker dollies to move around the compactcircuit and it lost power but did not show the flashing yellow no power sign.

Thanks for the help!
