Updating your game client and previous, unmodded saves
By default your Steam client will automatically update to the latest version of the game, build 42.22.
We work to ensure that previous save games can be continued in new versions, and for a completely un-modded, "vanilla" version of the game, your save game should work fine.
After updating, when you launch the game and select 'Continue' or 'Load', you will be asked to 'convert' your save for the new update. Once you click yes, a backup of your existing save is created in the same folder with '_backup' added to the file name. This means if you do have any problems, you have a backup automatically available.
If you have any issues with your un-modded, vanilla save, please post to our forums. Please note we cannot provide technical support for modded saves.
Modded saves and 42.21 temporary branch
If your existing save game uses mods, it's possible that some mods may not work with the latest build. We would still recommend converting your save and seeing if your mods work, as you'll have the automatic backup available if you have issues. You can also manually backup your save by copying it.
If you wish to continue to wait until mod creators update mods that you use frequently, you can continue to play on build 42.21.
In your Steam Library, right click the entry for Project Zomboid and click 'Properties', then select 'Game Versions & Betas' and select '42.21' from the list. This will automatically update your client back to version 42.21 and your save / mods should work.
