SAME DAY CAMPSITE VILLAGER INJECTION / SWAPPING OUT CAMPSITE VILLAGER
00523D48: campsite true/false status, essentially.
03 = there's a camper in the campsite!
02 = there's no camper in the campsite. sad.
To inject a camper that isn't there already, you MUST edit this byte to 03 for the game to even recognize there's supposed to be a villager in the campsite, before it will even acknowledge the villager you edit in. If you just edit bytes 0C and 0D (for the villager ID), the game will ignore you and refuse to properly spawn anyone into the campsite for you. If you're just swapping out a villager that's already in the campsite, this byte will already be 03.
