2023 Errata
From DominionStrategy Wiki
The 2023 Errata changed cards giving extra turns to never allow more than two turns in a row. This affects Island Folk, Journey, Mission, Outpost, Possession, and Voyage but not Fleet or Seize the Day.
Trivia
Reasoning
DXV has gotten sick of being able to take 3+ turns in a row, every single turn, for the whole game. Fleet and Seize the Day are only once a game, which is why they're safe.
