How to Reset or Wipe a Project Zomboid Server Map

How to Reset or Wipe a Project Zomboid Server Map

There are three ways to reset a Project Zomboid server: wipe everything (hard reset), wipe the world but keep characters (soft reset), or reset only specific chunks. This guide covers all three with the exact paths and how to keep players.db if you want characters preserved.

Stop the server first. Every reset method below requires the server to be stopped. Edits to a running server's save folder get reverted on shutdown.

File layout

A Project Zomboid multiplayer save lives at:

/home/container/Zomboid/Saves/Multiplayer/servertest/

Inside, the important files and subfolders:

The servertest folder name matches your server name. Renamed servers will have a different folder name.

Hard reset — wipe everything

The simplest reset. Players lose characters, the world regenerates fresh.

1. Stop the server
2. Open the file manager and navigate to /home/container/Zomboid/Saves/Multiplayer/
3. Delete the servertest folder (or rename it to servertest_backup)
4. Start the server — it generates a new world on first boot

Time: instant. Players reconnect to a brand-new world with brand-new characters.

Soft reset — keep characters, wipe world

Players keep their levels, inventory, and traits but spawn into a fresh map.

1. Stop the server
2. Navigate to /home/container/Zomboid/Saves/Multiplayer/servertest/
3. Copy players.db to a safe location (e.g. download it via SFTP)
4. Delete or rename the entire servertest folder
5. Start the server, then immediately stop it once you see SERVER STARTED (this generates a fresh servertest folder)
6. Stop the server again
7. Paste the saved players.db back into the new servertest folder, overwriting the empty one
8. Start the server

When players reconnect, their characters reappear at the default spawn location with all stats intact.

World wipe but keep map progress — reset zombies and loot only

Useful for "fresh start" weekends without losing built bases. This isn't a single-click operation:

1. Stop the server
2. In /home/container/Zomboid/Saves/Multiplayer/servertest/, delete only:
   • zpop_*.bin (resets zombie populations to original spawns)
   • reanimated/ folder
3. Start the server with LootRespawn = 2 in servertest_SandboxVars.lua for one cycle, then revert

Player builds, loot they've gathered, and the map remain.

Chunk-level reset — refresh a single town

You broke a town with too much building, or want to refresh loot in just one area:

1. Identify which chunks need clearing using the in-game coordinates (press F11 to see X,Y)
2. Each chunk file is named map_X_Y.bin where X and Y are cell coordinates divided by 300
   • Example: a player at X=10500, Y=8700 is in chunk map_35_29.bin
3. Stop the server
4. Delete only the chunks you want to refresh
5. Start the server — those chunks regenerate on first visit

Don't delete files ending in _player. Those store player-built structures.

Reset bans and whitelist — but keep the world

If you only want to clear bans/whitelist without touching the map:

1. Stop the server
2. Delete /home/container/Zomboid/db/servertest.db
3. Start the server (it regenerates a fresh DB with no bans, no whitelist, no admins)
4. Re-grant your admin access via grantadmin in console

This wipes bannedid.txt, bannedip.txt, and the SQLite admin table — make a backup first if you might want any of it back.

Verify the reset worked

After reboot, connect with a fresh-character or your saved character. Things to check:

• Spawn location matches the configured spawn region
• Loot density matches your sandbox FoodLoot/WeaponLoot settings
• Zombies present in the expected numbers
• Time of day matches your StartTime sandbox setting

If any of these look wrong, the wipe didn't fully take — usually because you missed deleting one of the files.

Common pitfalls

Players still see their old base after reset. You wiped map_*.bin but missed the chunk files ending in _player. Delete those too — but be aware this kills all player-built walls and structures.

Characters disappeared after a "soft reset". You forgot the players.db copy step, or you copied it back into the wrong folder. The folder must match servertest (or whatever your server name is).

Reset succeeds but server crashes on player join. A mod broke during the wipe. Check /home/container/Zomboid/Logs/ for the exception trace and look for Mod "X" references.

The new world keeps spawning at the same coordinates I want to escape. Your spawn regions are defined in servertest_spawnregions.lua. Reset that file too if you want the default spawn region picker back.

Backup before any reset

Always download a copy first. From the file manager, right-click the servertest folder and download. Or via SFTP:

sftp> get -r /home/container/Zomboid/Saves/Multiplayer/servertest /local/backups/

A typical multiplayer save is 50–500 MB depending on world exploration.

FAQ

Will resetting affect my mods? No. Mods live in a separate path (/home/container/Zomboid/Workshop/) and aren't touched by world resets.

Can I reset without losing the bans list? Yes. The bans list lives in /home/container/Zomboid/db/servertest.db (SQLite). It's separate from the world save — wiping the map doesn't touch it.

How often should I reset a long-running server? Most servers wipe quarterly. Sandbox LootRespawn settings handle most "freshness" needs without a full wipe — only reset when builds get out of hand or you want a real reboot.

Does deleting map_zone.bin reset zombie distributions? Partially. zpop_*.bin is the bigger lever for population resets. map_zone.bin defines forest/urban classification.
