Dynamic Spawns Grace Period bug

First off, I’m using a relatively recent version off the github I compiled in Code:Blocks a few days ago. The wiki guide claims that there is an hour long grace period in which zombies don’t spawn.
Zombie children, however, spawn in parks immediately at the beginning. Since I had a half dozen parks surrounding the only military surplus in town, my Hardcore+Glass Jaw trait character was quite dismayed to learn this, as he can’t fend off anything in melee.

Yeah, that’s been around for a bit. Megastores & Hospitals have similar issues.
