Mysterious Island #16: 5-6: After this ship explores this island, swap any number of treasure coins taken with an equal number of treasure coins chosen randomly from other wild islands.
This implies that the treasure you trade for must be loaded. What happens if you receive a UT that can’t be loaded, such as Wolves? I assume it would apply to any treasure received via the swap, and not to the treasures you took originally and didn’t swap? (because it occurs after exploring, and after step 8 – “Apply the effects of all revealed unique treasures.”)
Ex: Exploring ship takes 3 coins and wants to swap the final one. She gets Wolves in return – are the first 3 exempt from the effects of Wolves? (or another UT such as Bloody Gold)
