[2020] Omniscient Zombie Pathing

Originally posted by dichebach: My approach to bases is perhaps a bit different than others. I build one base, not a "main" and a "horde."

Simple. Fear of losing everything to a failed defense. When you have a Main base where you do everything, and a Horde base where you fight hordes, your main base is never at risk from a horde and so a failed defense really only risks the items on your character if you have inventory drop enabled, and the horde base itself.
