Crops are dying
Check water readings, sowing-season warnings and visible symptoms in Project Zomboid Build 42. Separate current observations from unknown causes.
The sow option is missing
Troubleshoot a missing sow action in Project Zomboid Build 42. Check the furrow, seed item, crop information and the action tooltip.
Water looks fine, but growth stops
Compare the water reading and displayed requirement for the same living crop. Check whether watering completed without assuming a universal dose.
Is this the wrong planting month?
Read the crop’s learned planting information and compare it with the sowing date. Check season warnings without relying on an outdated crop calendar.
A harvest gave no seeds
Check the harvest action and distinguish food from seed collection in Build 42. Keep crop-specific stages and unavailable information separate.
Did walking over the farm kill it?
Official 42.21 notes clarify that player footsteps do not damage crops. Keep that separate from other traffic and unexplained crop failures.
Heated water is still tainted
Water still tainted after heating? Check the container, heat source and fluid status after the Project Zomboid 42.21 purification changes.
The sink will not plumb
Separate a missing plumbing menu, an empty water source and unsafe water in Project Zomboid Build 42. Start with the symptom you can observe.
Generator fuel disappears too fast
Investigate fuel use with the generator’s live load, elapsed game time and sandbox settings. Compare one appliance change under the same conditions.
The fridge lost power
Check refrigeration after an outage and the 42.21 changes to fridge warm-up and bagged food. Avoid assuming a guaranteed safe-food timer.
Host must allow you to join
Fix the Project Zomboid host permission message: check the host’s Invite Friends list, Steam mode, matching builds and dedicated-server access.
Set up a dedicated server
A source-based Project Zomboid dedicated server checklist: Windows Steam Tools, matching builds, connection and save checks, with optional SteamCMD notes.
