Exact same problem. Game becomes unplayable on PS4 when it gets stuck on 4/5 clues in the Saving Caius Thorn mission.

Also my account info is not accepted in the login screen when I click "report bug" in game, so here I am.

Same here; searched all 3 locations, Magos was at neither.

Can't progress anymore.

And right after the 2.0 as well :'(

Hope you can fix this several months old critical bug.

I have this problem too. I think I visited the first location before the big 2.0 patch. I went to the other two afterwards. She wasn't at any of them. Now I don't have any pink markers on the map to visit. Clues are stuck at 4/5 and I can't progress the plot.

Please can you fix it?

My account/character name in game is DGresevfan. The problem is with my Crusader character. Is that all you need?

Hi the bug is not fix. I'm stuck too ! I've made more than 20 mission on Aethon system and Magos Biologis don't appear...

I've 4/5 clew, Crusader and on PC.

MEA culpa, I confound the system Aethon with the planet Aethon... There is no bug.

Managed to progress past that point, think it may have been an error on my part rather than a bug, but I got confused as I thought I'd sought the magos at 2 locations, then did a side mission when the magos was talking to me before I found him. Anyway, think I could have progressed.

Also wanted to say I love the game, it's brilliant! Thanks for responding

my  character is madjanie
