I use DMT to make the DLL.
Wandering hordes are disabled on bloodmoon. That's base game functionality. As an aide, screamers can't spawn hordes either during bloodmoon.
The spawning is... odd. So if you set 4 hours, ever 4 hours it will check if it's safe to spawn a wandering horde. Sometimes it does so immediately, sometimes it decides it's best to wait an hour. On rare occasions, it delays it for 12 hours. Still not sure why it does that and I need to investifate it more before I disable it.
The forced bloodmoons off is a seperate harmony patch you can just delete, but the point of this mod is to play it with bloodmoon off.
Logging is just for me to do debugging. It doesn't do anything else. Most of it's functionality is disabled because I don't need it.
