there needs to be a limit as to just how much a wander spawn will spawn in zombies, I played an inside lab start that took quite some time to get to the surface, only to find a wandering spawn happened outside the lab, while trying to stay alive and avoid the zombies and killing whatever i could, more and more kept on spawning in untill the game froze and crashed when the game couldnt spawn anymore zombies since everywhere it was trying to spawn was already filled
I love the idea of using wander spawns as it keeps places filled with zombies but as it is, its impossible to survive
