Money, soil, milk, and prices are host-authoritative. A client does not quietly rewrite the shared farm.
Install the same companions you care about on everyone who should see that chapter. A player without Soil will not have the Soil app. The farm does not crash.
Farm Tablet is per client. It reads. It is safe on a join. The deep desk is for the person at that machine.
Network Sync is the suite’s shared pulse when you want one clean multiplayer year. Without it, companions use their own events and still play.
If something “crashes”, read both the client log and the server log. Menu trouble often leaves the host looking fine.
