Aerdan and I tried playing a hotseat game of Outback Tycoon (the Civ 6 scenario) today. Unfortunately, the event triggers appear not to have happened, and OT relies on them to progress the game.
Specifically: finding gold did not trigger the Gold Rush eureka, and the turn 4 event to grant your first settler failed to fire. (No settlers means no cities means you’re stuck with just your starting explorer for the entire game.)
I am fairly certain this is not a bug in OT itself, nor in Civ 6’s hotseat play, as I am able to play a hotseat game of OT without PYDT and the event triggers happen.
