Put cores and any companion that writes money or sim on the dedicated host. That is soil, crop stress, dairy, markets, tax, income, fuel, workers, events, neighbours, co-op, depot, workplaces.
Farm Tablet does not start on dedicated. It is client-only. Players who want the desk install the tablet in their own mods folder.
Clients still need the zips for mods whose files they load. When in doubt, match the host’s companion list, plus the tablet on the client.
State Ledger and Network Sync belong on the host. A pure client has no save folder. The host is the year.
