Anyone had this?
I can't access the quest via the notice board, the note has a cross marked over it.

Are we meant to clear the game before doing this or....?

The cross marked over it is supposed to be there, if I remember correctly. Make sure that you aren't currently doing a mission, or you won't be able to start it.

Wondered if it was because I was doing a quest.
Unfortunately, I went to do one of the other quests I have, but it popped up something along the lines of "If you do this quest now, it will clear all side quests & you won't be able to do them afterwards"

:(

You have to complete the first set of Point of No Return missions before the christmas mission unlocks, which it seems to be where you're at now.

Guess I shouldn't have restarted play through before this patch.
D'Oh! ;)

No, you don't. When I did the Christmas mission it was before the first Point of No Return mission for that playthrough.

For me, the holiday quest was available only after the point of no return, and I started my firs6t playthrough just this week. BTW, the mission is still available, as we didn't get the latest patch on GOG.

I'm back to the game for a little while. I was at the first encounter of this old demon women friend, planning to search for the body of Kamiko. I finished to talk, exit from this location by the "vortex" thing, and saw the "winter quest". I did it and finished it, and since it's like I can't turn back to the main mission. No objective available nowhere, nobody to talk, no more vortex, and only my old quests where I can go back for fun...

I'm stuck in the story without any option to continue. :(
