The new Shattered Planet https://mods.factorio.com/mod/skewer_shattered_planet is in the wrong location and has its connections backwards with Interstellar Travel enabled. Janus and the Metal&Stars system connect to the "Lost Beyond" which is supposed to be the new end of the galaxy after the shattered planet, and nothing else connects to the shattered planet itself.

I noticed after this Shattered Planet was added to Enable All Planets Lite.

Thank you for your time.

Mod is not deprecated and no longer even loads. So, there is nothing I can do to fix this.

I'm not sure what you're saying? Neither Interestellar Travel or Shattered Planet mod are marked deprecated and I can load the game with both just fine in my current save?

Still deprecated. The deprecated dependency prevented the mod from even loading last time I tried.

Weird, I just tried uninstalling and reinstalling shattered planet and the assets mod and it installs fresh and loads just fine alongside Insterstellar travel. (Aside from Shattered Planet being disconnected from Shattered Planet approach.)

There was some problem a few months ago with the assets mod so that may have been the cause of your previous issues but it's fixed now.
