- About the missions no longer giving faction standing
For the Amarr circle it seems "Agent: Ilia Abazen" will only give the Robots mission after the first run. (I gave it 7 tries in total so it's very unlikely this is caused by chance).
For the Caldari circle "Agent: Enanato Imeri" and "Agent: Yrmek Penola" seem to simply stop handing out missions after the first circle.
I have not run Gal/Min ones because why bother ;D
