Supported Maps and Packs
RLRM works on virtually any map out of the box. It does not need to be on a list. The maps below are special only because they add their own custom animal types or breeds, which need built-in support for those extras to get the full RLRM treatment, including genetics, breeding, and reproduction. On any other map, the standard animals just work.
Maps:
- Hof Bergmann, ducks, geese, cats, rabbits, alpacas, and quail with full breeding support
- Witcombe, UK breeds, Jersey, Gloucestershire Old Spot, Texel, Suffolk, and Blue Faced Leicester, with full breeding support; Hereford heritage profile
- Le Mechet, French breeds, Charolaise, Montbeliarde, Simmental, and Vosgienne, with full breeding support, not compatible with Cow Breeds Pack unless you use the latest development version, as both replace the cow husbandry config
Animal Packs:
- Cow Breeds Pack for RLRM, additional cattle breeds
- Sheep Breeds Pack for RLRM, additional sheep breeds
V1.4.0.0
This is the disease release. The disease system has been rebuilt from the ground up: an illness now runs day by day, can hide for a while before any symptoms show on harder settings, and is tuned by a five-level difficulty setting. Four new diseases join the five existing diseases, including colic, the first disease for horses. A sick animal can no longer be sold or sent to the butcher while it shows symptoms. It must be treated or culled from the Diseases dialog.
Update notes:
- Every disease infection, immunity, part-way treatment, and CVM carrier in your save is cleared on first load because the new disease records cannot read the old ones. Your herd starts out healthy, disease-free, and CVM-free.
- The Diseases setting becomes a difficulty level: an existing save lands on Normal, or Off if diseases were off. The Disease Chance setting is gone.
- Nine diseases: avian flu (HPAI), BRD, pulpy kidney, and colic join mastitis, CVM, foot and mouth, PED, and avian flu (LPAI).
- A hidden phase: on Hard and Very hard, a newly infected animal looks healthy for a while before its symptoms show.
- Five difficulty levels: Off, Easy, Normal, Hard, and Very hard, plus a Choose Diseases list to switch single diseases off.
- Treat or cull: a sick animal cannot be sold or butchered while it shows symptoms, by you or the herdsman. The new Cull button removes it for a share of its value.
- Illness affects more than milk yield: growth, breeding, eggs, wool, and manure all suffer while an animal is ill.
- A sick animal that shows symptoms can no longer be sold or taken to a butcher, by you or by the herdsman. A herdsman sell rule for animals with any disease now sells none, so switch it off or change its filter.
- Foot and mouth treatment is now a one-month course like every other disease, instead of three months.
