I finished the T1 weekly and the solo weekly. I've started the Heroic T2 weekly and the event heroic weekly. So far so good when i picked up the quests i was able to pickup the overland zone weekly for the air zone as well. The npc does show the option for solo still, but doesn't list any quests in it I also tryed to get the overland weekly from sharing but it says i'm allowed because i have a active mission from this quest giver ... yes i have active weekly quests but they are for the heroics I guess that means i have to finish the heroic weekly before i can start the solo overland weekly and next week i pick up the solo weekly before i pickup anyother weekly :/
This is actually a bug with how the Planar Chronicler Vol. 2 checks your solo outdoor missions, and will be fixed next hotfix. Thanks for reporting it!
