Oh! Yes, Festive Fish is replacement for disappeared 1* Giant Crab. From Midoki: The Festive Fish is a known issue which sadly didn't show up during testing due to affecting only a specific sub-set of players. Unfortunately it doesn't look like it's going to be sorted this side of Christmas as it requires quite a substantial and tricky fix - the quests will be around for a fair few weeks yet though. We can't find any issue with the Santa or Ice Ships - as far as we can tell, people are being thrown a bit because they both have much longer respawn timers than previous and existing events (up to days rather than minutes/few hours max), plus it seems that some people are missing the Santa ship because either they've not uncovered his location on the map yet, or because from a distance it looks like a little barge (we'll have to make his ship more conspiculously fabulous next year!). The testers are still looking into it though, and we're making notes and listening to feedback on how to improve future events. Again, apologies to all those who are affected, hopefully we should have a fix soon!
