This is a fun one:
First, place a teleport pyramid somewhere in the world, and then wander off elsewhere. Then have Scarlett as your lead character, and try to use the second pyramid which is in Roderick's inventory. Even if all your characters are linked together, Roderick will ping off all by himself to the pyramid's location, and then a second later, he'll ping off somewhere else (watch the party-member direction indicator) and come rushing in from offscreen.

Good luck, QA department!
