Game worlds are back online! We have fixed a critical issue through which some items (classification 2) could be obtained with tier 1 from certain chests. Due to the fast shutdown of game worlds to investigate this matter, only 21 items in total were created that way and further ramifications could be prevented. We have set the tier of the affected items to 0 since it was not gained through fusion. We sincerely apologise for the long downtime which was necessary to investigate and address this matter properly.
