No Santa ship and festive fish on the map

Why I can not find Santa ship and festive fish on my map?

 

It's a mystery to midoki as well...they also can't find the reason...maybe those ships have left midoki because they didn't pay them

 

I found the Santa ship at a far flung part of the map

 

Santa and the Ice ship move around a bit. The Fish, already been mentioned. Some people just can't see it because it doesn't exist for them. Supposedly that will be fixed in time to get the quest before it goes away.
