My words literally betray me.
I wanted to clarify that I've been playing this right:
When you complete a Discoveries card, you draw a new card before re-rolling your triggered dice. Is this correct?
The rules are written in that order and it is how we played it. it is consistent with picking your discoveries card at the start of the game before rolling dice.
the rules don't explicitly state that everything in the end of exploration is meant to be done in order though. But my best guess is that you are playing it right.
(couldn't hurt to have official clarification though)
