Changes

Inbreeding occurs when an offspring is bred with either of its parents. It's typically unavoidable in small herds but after 3 generations the requirement to inbreed will be removed; it's advised to seek neighbours to begin a herd if one wishes to avoid inbreeding. There is a chance to add extra negative traits to animals bred with their parents, which won't count towards the regular trait limit. Some players have observed that deceased parents will not count towards the inbreeding check at the time of birth. "I have often used it as a method of breeding, to kill the old parents when I had too many horses that had a parent in common. After the parents are dead, you can breed and get normal horses. Leave the parents alive and you get lots of bad traited animals."
