Guild Wars 2

So up near the mastery point in The Bitter cold area, you can thaw out a mother and her cubs for a snow leopard in your instance, but only one cub is appearing and I’ve checked and unfroze them on and off for the past 2 days now and still nothing.

The frozen cub to unfreeze that is alive and becomes part of your home instance is at a different location in the cold area. It’s where you can glide down from.

That is the correct area but that cub can move around since it will follow whoever unfroze it around until it gets frozen again.

For me the mother and cub (shown in that screenshot) died when unfrozen.
As Blude.6812 said, there is another frozen cub.
That one stayed alive when i unfroze it.
And that one i presumed was the needed to get the cub in the home instance.

I just saw the domestically-inclined cub wandering below the usual area — someone had glided/jumped and it followed.
