When accelerating the Invader Deck, what happens if one of the cards that would be accelerated can't be discarded (e.g., the "Salt Deposits" card from Habsburg Mining Expedition Level 4)?

Ignore that card when determining which cards get discarded (so another card gets discarded instead, usually the next card of that Invader Stage).
This generally only matters if the deck is accelerated in the middle of the game, such as in the "Despicable Theft" Scenario.
