You've started a new singleplayer game, and decided later on to try the Hydrocraft Mod. You decide to farm and find out the growth phase remains at 0, and when you water the crop it jumps all phases in a matter of minutes.

I found a solution! You can combat this by doing a hard reset while keeping your base & character!

1. Make a separate folder somewhere so you can back up your base files & character file once you find them. Bring up PZ Official Map.

2. Startup PZ, and start new solo gameplay. Don't matter what character you won't be using it for long. Choose the map where your base originates. Enter the game.

3. Spawn to your base, if it has a POI on PZMap you can use a utility mod such as Necroforge to teleport to that POI. (Mines was Farm to The West. Didn't have to travel all the way to it.) If you by chance have a base setup that's not a POI in PZMap. That means you will need to spawn to the nearest to it. This eliminates having too many files to look through that will be needed later on.

4. Once you've reached where your base would be on the new gameplay. Explore around the area. (Roughly the perimeter/area of the base.)

5. Once you've explored where your base should be. Exit Save. Then go to your new save file. C:\Users\USERNAME\Zomboid\Saves\OneWeekLater\NEWSAVENAME (If you don't know your new save's name. Launch PZ again and go to Load. There you will click on the new save and it'll give you the name of that save.) Inside you will see files such as map_XXX_XXX.bin. These are the files of the map you've recently explored! Which includes the map files of where your base would be.

6. Now the part where things require some patience. Have your Backup Folder open, New Save folder, and Old Save folder. Bring up the PZOfficial Map. Search for the coordinates of your base, these numbers play a major part and finding your base in the map_XXX_XXX.bin files.
EX: Farm to The West is 8599x8824
You will then check your new save folder and search for map_859_882.bin file (That's the coordinates, the last number will not be in the file don't worry). That's a piece of your base. If you continue to hover around the outline your base (do a big square if need be). You will get a rough idea of what map files you would need. Between 859_882 and up or down, depending on the coordinates you get from the big square you made on the PZMap.

8. Once you've compiled the needed coordinates you need to figure out your base files. Check your new save, and look for the file that has roughly the coordinates of your base. From start to finish of the map_.bin files that's your base files. 859_882, 859_881, 859_880, etc etc.

9. Now, look over to your old save folder. Match the files in that folder to the ones in your new save. Once you've got all highlighted. Copy the old map files from your original save folder. Paste them into your backup folder. (Just in case you need to go back and get extra pieces and not the same ones again.)

10. Once they are backed up, take those same old files and paste them into the new save folder. It should overwrite. Go back to your old save folder and copy your map_p.bin file. That's the original character that you're importing into the new save. Paste it in the new save folder. DONE!

Once you load the new save you should have everything you had from your old save into the new game. Beware of any new zeddies in the area. Containers remain the same on that lot. Whatever you've built should be there as well. (IF your base is not completed, you have to go back and get more files from your old save folder imported to the new save. Complicated I know but it's worth it if you don't want to lose hours of gameplay!)

Hope this helps!
