If you are playing with Full Autonomy it is important to "Vamp-proof" your house, especially if you have 8 vamps. By Vamp-proof I'm mean keeping vamps from killing themselves, like you would "child-proof a house for a baby. I've had 4 vamps go up in flames, so learned this the hard way. If you have Autonomy turned off it isn't necessary.
- Clear away any dense landscape features, so you can see them wherever they are standing if they go outside.
- Don't have anything for them to sit on outside their house.
- Don't have anything for them to look at outside their house.
- Don't place telescope outside the house continuously. Use it then put it in family inventory.
- At 6am in Forgotten Hollows check to see what your vamps are doing.
