Working on a simple map, and earlier today, I screwed something up, and now, when running my map, round 1 will not start at all, so zombies don't spawn.
I assumed it was something to do with the extra spawnpoints and windows I added, so I tried deleting all those, and instead opting for one zombie spawnpoint inside my starting room, just a zombie_riser spawn set to find_flesh, but even then, with just one spawn point, round 1 won't start.
My full spawnroom is covered with the starting info_volume, so I'm not sure what's causing this.
