Magos Biologis not found in the three locations


I played the story mission "Chapter Two , Saving Caius Thorn, Search for the Magos Biologis" in coop and the magos was not found at any location. Now I have no new story missions (I still should search the magos biologis at the three locations) but  that is not possible.

Please fix this!

I found out how to fix it.

The game asks you to go to Aureus system in the Triglav subsector but it actually meant Aetheon system in the Tenebra subsector.

Took me about an hour of trying different things to fix it but i believe this will fix this for everryone else too.

Hope it helps
