I'm trying to make sense of this new timing ruling. Obviously I thought it was both more intuitive, clearer and easier to understand when I assumed that "end of turn" happens as the last part of Clean-up.
1) What about Wine Merchant? It follows that "at the end of your Buy phase" is after your Buy phase. Is it in your Clean-up phase then? Else it would have to be in-between the two phases, but having stuff in-between phases seems really odd. I mean, with current cards it doesn't seem to matter, but some cards (like Crown or Peddler) care about what phase you're in, and having "at the end of your Buy phase" happen when you're not in any phase, doesn't seem like a wise choice. Then again, having it in your Clean-up phase doesn't seem much better.
2) According to the rulebook, "the game ends at the end of a turn, if either the Province pile is empty, or any three or more Supply piles are empty." This would seem to mean that end-game is checked at the same time as Baths. So can you choose to end the game after you take 2 VP? This seemingly similar timing (based on the phrasing) was already there of course, but with the assumption that Baths actually happens in your turn, it seemed clearer that end-game is checked as the last thing in your turn, after Baths.
In any case, a literal reading would seem to suggest that you can choose to resolve Baths first, whether you go by the new ruling or the old assumption. Or: end-game check is not something you can order, it's always last; in which case you always get the 2 VP from Baths, whether you go by the new ruling or the old assumption. But having Baths (Possession, Save) and end-game check both happen after your turn, and end-game check being last of those things, make it pretty fuzzy that there are other after-turn things happening after end-game check.
