"13 possible spawn points" when there's a 100+ in the spawnpoints.lua

[Ray_DB]

Hey, I've been trying to set up additional spawn points on a map I want to use in an event. By default, there's only 5 spawn points in the spawnpoints.lua. I've added a ton of extra spawn locations, but in game I keep respawning at the same 5 or so buildings. I checked the console, and every time I respawn it says a message, "NUMBER possible spawns". Sometimes it's 13 possible spawns, sometimes it's 5, it's completely random as far as I can tell. I had a theory that it only allows a player to spawn somewhere if it's clear enough of zombies, but I have no way of verifying.

Can someone shed some light on how the game selects a spawn point for the player? And how can I make the other spawn points "usable"?

This is my current spawnpoints.lua file, if I just messed up the formatting or something maybe someone could point it out.
