What happens if you reach an end card with both doors?

Question

If you construct a path from a ladder to an end card with a blue or green door in the path, the end card is flipped. If the card is the gold, all dwarves on that colored team (blue or green) win, as does the boss and profiteer.

What happens if you construct a path from a ladder to an end card while both doors are in the path?

Answer 1

The game designer, Frederic Moyersoen, discusses the answer to that question on BGG. Essentially, only the Boss wins

If there is a path with a blue and green door, the boss is the only player who can win through this path (4 points). This can be a winning strategy for the boss.
