Hello there @bielik01,
Thank you for taking the time to share your feedback and concerns with us. I've passed this along to the development team, especially your concerns about a lack of a changelog and no warning prior to the hot fixes release. We apologise for any confusion that may have been caused by TU 1.2.2.1.
To my knowledge, the Ostara items should not have been deliberately removed from the game. I've reported this issue to the development team for them to take a closer look at. Once we have any new updates to share regarding the disappearance of the Ostara rewards, we will let you know within this thread.
If you have any further questions or concerns, please don't hesitate to reach out.
Thanks!
