My problem are 2 actually.
1. The side mission in Hive AG3 (Arrack space). Althought I continued with the story the side mission is not given, hence I cannot tkae the key for the locked Honnaing system. Any suggestions? (Note that the side story in Hive B52 is given and completed successfully)
2. I completed the story line searching for the scanner in GAB'HAR, Oc'To Space. However, only 3 systems where unlocked. The rest of them are still locked and no matter to which of these 3 systems I jump new navigational data are not provided. Any ideas?
I continue with the story line and I check back, but no progress is made in the above issues.
Thanks for your help.

Found the answer in the forum for the GAB'HAR system.
I apologize for the double post. I found out the name of the system while writing the post and due to the strange name I missed the post.
The problem with the Honnaing system is open. (I checked the map from the other post and noticed that he actually manage to comple it)

The sidequest to unlock Honnaing is given by Jiju in Tinmaung. He tells you of this sidequest as part of the main quest.

Good for you ... but where? Can you please let me have a link? I´ve the same trouble.

Yes, But, once you have Unlocked the Honnaing System by getting the side quest from Jiju and completing it, and you have collected the Artifact from Honnaing, what do u have to do to get the reast of the system's unloacked in the GAB'HAR Octo Cluster.
I mean, there are 3 systems opened that you get opened from doing some of the storyline Missions. But I have been doing quests/Missions from each of those 3 systems for a couple of hours now and no other systems unlock at all.
Usually when you enter a new system, the extra " ? systems " start to unlock as you Hyperjump close to them or by doing missions etc, but with the GAB'HAR Cluster, that doesn't appear so.
I have also completed the storyline mission when you have to go to the system and you get attacked by the Thul, thinking you were set up by Jack, but then he comes and helps kill them. I got his follow up mission from speaking to him on the stations communications. I am about to follow up this part of the storyline right now and hope that has some kind of effect.
If ayone knows of any information that I need to know about getting the systems in the Octo GAB'HAR Cluster to start unloacking (opening) except for the 3 original systems, please by all means tell me. I really would like to know what is meant to be done to begin opening up these extra systems as there are plenty of Artifacts that I could upgrade my Darkstar One Ship 2 more times, possibly 3. So you can see how this is very important to me. Thank you for hearing my question. Have Fun, Take Care and Enjoy. :)

I was able to unlock the systems. I completed that main storyline mission and was able to fix it. Thanks anyway for the help, well help I may have got. Thank you :)
