Re: Why did they take out the hybrids in TS4? I had a whole entire world with hybrid
@1003811392321 I am wondering if your hybrids were through natural game mechanics {happy accident} of if a mod was involved.
Within the mechanics of the game hybrids (except aliens) are not intended but still happen on rare occasions.
By design occult types like Vampires, Mermaids and Spellcasters are not intended to be a hybrid mix of any of these in combination.
Personally I did have a Vampire give birth to an Alien by abduction. The child had both Alien and Vampire traits/powers but the game did not officially recognize her as either. There were a lot of issues with that child. When she became a teen I cured her Vampirism and she was finally recognized as full Alien. I saved the hybrid child as a toddler and test the household from time to time. I have yet to see her be "cured" of being a hybrid.
In any case if Mods were used for your hybrid world I suggest you present your issue to them. It could be that an update can return your world back to the way you like to play.
