Ok, I've talked to Talana, gotten the Penetrator fleet back, and been told to tell the Mycon about Organon. So, I go back to Beta Brahe. If I talk to any old Mycon, I get the usual dialogue options. If I go to planet I, I get the following options:
What makes this place special to you? There is a world at the star Organon. We'll just be going now.
Selecting '2' gets the response:
"This is a special place. You must go. Now."
Then I leave, but if I come back for the sun device, the Mycons are still there. Is this an UQM bug, or am I doing something wrong?
I had the exact same problem. I just submitted it as a gameplay bug, cause i remember the gameplay on the PC at this part of the story arc, and the mycon are supposed to head to Organa to get ambushed by the syreen... and they aren't moving.
Congratulations on being the 1000th person to think there is a bug.
If that planet doesn't work, why don't you try the actual Mycon homeword instead. They'll be much more interested in what you have to say. I promise it will work to your satisfaction.
