Purpose of change

I decided to add a new start to the apartment, since it seemed strange to only be able to appear on the roof, and not inside a house.

Describe the solution

Add a new start to the stage by choosing one of the apartment floors.

Describe alternatives you've considered

Testing

I tried several times, and it always appears in a house in the apartment, in general a zombie never spawns inside the house.

I just put the original number back for you, I don't really mess with Github CLI and proper reverts that much.
