I had a mad king’s clock tower jumping puzzle achievement in the Historical section (from the first Halloween) before the update. After HoT, that achievement is gone. I understand moving achievements to Historical, I do NOT understand deleting them. I now have no record that I did that jumping puzzle, and even if I felt like doing it again, no achievement would be given.
But for the record, I do NOT feel like doing it again. Doing it the first time required hours and hours of frustration, and was an achievement I was justly proud of. Now its gone .
