I've just finished January game. The instruction for end game for either case says:

> 
> Discard all City cards. These all reset for the start of the next game. Do not put any Legacy cards back in the Legacy deck, even if playing the same month. Just continue where you left off in the Legacy deck.
> 
>

This would imply that in February I start the game with the unused event cards at hand. Is that correct?
