My opponent cast a spell that would cause a board wipe. In response, I cast Teferi's Protection, which says that UNTIL MY NEXT TURN, my life total cannot change and my permanents phase out. Specifically, Phase out also says they phase in on my next untap step.

My opponent then cast a spell giving them additional turns. At the start of their next turn, all of my permanents phased in despite me not having an update step. Per Teferi's Protection, none of my permanents should have been able to be affected, and they were able to instead exile each and every one of my lands. This made me lose the game.

Please fix Teferi's Protection to properly last til my next turn.
