Weekly quest disappeared from quest log

I had completed two dungeons from the weekly Timewalking dungeon quest, and with nearly six days left before it expired, when the quest disappeared from my quest log. I didn’t drop it, had definitely picked it up, and in any case the questgiver Caretaker Kah-Toll is not offering me the quest again, nor asking how progress is going, nothing. Anyone else seen this?

Hey there Chaerea,

Looking into this, for you, it seems that you actually completed the quest. Is the issue on a different character maybe?

Thanks a lot for having looked into this, appreciate it. I’m clearly going mad as, yes, I completed the quest on this character. It was another character I am part-way through the weekly on.
