Where are my troops dispatched to the Stash?

Offensive Units sent to сapture the Stash and Defensive Units that return with the Resources from it are sent directly to the owner's Catacombs.

In case the Stash becomes vacant or disappears before the Attack, Scout Mission or Reinforcement reaches it, the Units sent to it do not travel back to their owner's Stronghold but are immediately sent to the owner's Catacombs.
