I can't finish The Lands of Always Winter quest

[Swordancer]

Im trying to finish The Lands of Always Winter quest, but I can't find White Walkers anymore. I saw them couple game months ago, but someone probably defeted them and I can't find them anymore. I even enabled cheat mode to see all units on the map, but they are not there. I cannot restart this quest becouse it is wasting more than 100 days in game.

Is there any chance that those White Walker party will resspawn it self again? I mean the one connected to the quest.

It is latest version of mod.

Bad news... nope.  I have heard whispers that you might be able to accomplish it when the White Walker Horde arrives, but I am not 100% certain of that.  If anyone can confirm this please post.

The white walkers don't respawn but don't worry they will still invade.

Ok, thanks for anwsers. Would I be able to accomplish this quest or not? When they invade Westeros I mean.
