We downloaded a hot air balloon mod for Atlas thinking that it would help us easily get from island to island inside map segments instead of always having to take the ships back out and risking getting stuck in shallow water. So I crafted the balloon, and it spawned about 10 feet in the air and fell to the ground. I was a little concerned when it hit the ground and made an animal distress sound, but we got in the balloon and headed towards the nearest island. About half way across the water, the balloon ran out of stamina, crashed into the water and drowned. Apparently it was a modified animal file, but not modified enough. Despite being stuck in the middle of the ocean and completely doomed, we couldn't stop laughing that our balloon had gotten tired and drowned.
