Game Lock Up

Locking Up is a bug exclusive to Creatures - Raised in Space that is caused by the Ettins within the game and also seems to be scripted into their behaviour.

The lock up occurs whenever an Ettin enters the Marine Terrarium and throws a star into the ocean. As soon as the star comes into contact with the water, the entire game will lock up, making it entirely unresponsive, and the only option is to reset the Playstation Console. Unfortunately, the only known way to prevent this annoying error is to never enter the Marine Terrarium once the Desert Terrarium has been unlocked.
