Lose Buffs in Late Stage TFT

So after dragon phase I had 6 Nobles 4 Knights and 2 Imperials. Out of no where my Nobles/Knights buff decreased to 1rst stage buff. I havent seen never seen this happen before. I was 1rst place then lost game to assassins cause my buffs; mainly my noble buff was diminshed to 1rst stage buff. It also happened to one other player that I know of in game. There were only three of us left... Has this happened to anyone else? P.S- Already reported, just adding thread to the community.
