A lot of people complain about spawning in prisons and hard locations, and I've got a cool idea that could fix this. Instead of just regular and casual spawns, separate it into different difficulty levels. For example, Easy spawns would be houses and businesses such as diners that are within city limits and close to many loot spots. Medium spawns would be isolated areas outside of towns or places that require you to walk for miles before reaching any loot, such as the cabins in the woods (not including the ones near a well) or some of the industrial discricts in Louisville. Hard would include all of those notorious spawns people seem to hate such as prison/jail cells, and that hidden governmental facility West of Rosewood would be a great place under this category since it has insane spawn amounts and is one of the most isolated places out there.

Also, I would like it if you could find a workaround for zombies not spawning in your spawn building. This system is fine if you're spawning in a small house or something, but when you spawn in a prison or a mall or anything of that sort it makes the whole building empty. Maybe for those types of buildings you could set the spawn point outside of the building, then teleport them in to circumvent the system?
