Wandering NPC's can get stuck in a loop where they reset every time you enter and exist a new territory and getting them unstuck can be a real pain. I had that same problem with Pirate Princess.
Bird H Scene doesn't work for me either.
The game has a memory leak that can slowly build up over a few hours, and the engine can't handle more than 2gb of memory at a time, so when assets stop loading it's a good sign to restart the game before it crashes. Restarting it resets the memory usage to normal.
The icon at the farm indicates which princess controls the farm, often a good indicator that the Insect Kingdom is about to arrive is when the Insect Princess starts controlling it.
