Quest bug, does not show in ToK, unable to take, unable to share

[Alteren]

Hello, on my character Alteran (dok) the quest All the King's Horses (Reikwald Fort Quest for Destro) does not show in my ToK. Others have been unable to share it with me (states I am already on it). I also cannot pick the quest up from the NPC (doesn't show any icon above head). I assumed it just wants showing and would still give credit, but after taking the fort, I did not get completion and the NPC in IC does not show an icon above head or allow completion.

It has been like this for 2 days now. I have done the quest many times in the past without issue. I only have 7 active quests in my ToK. I have tried reloading, changing characters and back, and doing /stuck.
