Hello
When choosing the first xenogene to add for the clone. I always get this error :

Exception filling window for Dark.Cloning.Dialog_CreateClone: System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

Any idea ? If you remove the first xenogene that you just selected the error stop. Until you enter a new colonist to clone and add a new first xenogene.
