Vampires stand in the sun burning
When vampires for whatever reason gets out in the Sun (Empty Thrash, Returning from work) and a toddler/child decides to interact with them they will stand there burning until the toddler/child makes his/her way out to them. This can cause them to burn to death if Vampire Energy runs out. If a toddler starts on another floor than ground it takes so long for them to pass stairs that it is almost certain to happen. Usually I catch it in time and can cancel the action and order the adult Vampire indoors. A few times I have had to reload a save game. Not fun when I had just played a couple hours.
Though this is not a Bug as such, EA needs to fix this.
For feedback and ideas, it's best to use the official forums as that has sections for that
