The company decided to remove a number of items and disable quests. The fact is that due to a patch in the Ravenstorp Viking settlement, the game began to crash. Since the city is one of the main locations in the game, the developers decided to roll back the innovations.
A message from Ubisoft states that items added with the Ostara Festival will be temporarily unavailable. The team is currently working hard on a hotfix that will allow you to enjoy the update to the fullest.
We’re deploying a server-side hotfix to address a rise in crashing near Ravensthorpe. Settlement decorations will be temporarily removed and Ostara Festival quests involving decorations will not be completable. Thanks for your patience as our team releases a permanent fix soon! pic.twitter.com/gYG7O8dvF3— Assassin's Creed (@assassinscreed) March 20, 2021
