Too Many Landfall Triggers
PC
Game crashes (or times out?), when handling large (~5000) landfall triggers at a time.
Historic Brawl. With 'Phylath, World Sculptor' and 244 'Scute Swarms' in play, I played 'Traverse The Outlands' finding 20 lands to put into play. The resulting triggers first froze the UI, then roped my opponent, then began to stack/count triggers in the UI, then 'Traverse The Outlands' was put into my graveyard (or maybe this happened before the UI triggers started?), when the UI finished stacking triggers (after a very long time) the 'Phylath, World Sculptor' trigger targets hit, while completing these triggers the game exited without a Defeated/Victory screen, taking me back to the home screen.
Game was laggy and exited to home menu without completing game.
