Please.
When I restart the server, I have to replenish them all.

{ "Water Jug ML Capacity (vanilla: 5000)": 25000, "Water Barrel ML Capacity (vanilla: 20000)": 100000, "Water Bucket ML Capacity (vanilla: 2000)": 10000, "Water Pump ML Capacity (vanilla: 2000)": 10000, "Add Amount Of Water To Water Pumps": 1000, "Add Water To Water Pumps Every X Seconds": 5.0, "Water Purifier ML Capacity (vanilla: 5000)": 100000, "Water Purifier (Powered) ML Capacity (vanilla: 5000)": 100000, "Large WaterCatcher Stack Size (vanilla: 50000)": 250000, "Small WaterCatcher Stack Size (vanilla: 10000)": 50000, "Add Amount Of Water To Water Catchers": 1000.0, "Add Water To Water Catchers Every X Seconds": 5.0 }

Fix your json error

{
  "Water Jug ML Capacity (vanilla: 5000)": 25000,
  "Water Barrel ML Capacity (vanilla: 20000)": 100000,
  "Water Bucket ML Capacity (vanilla: 2000)": 10000,
  "Water Pump ML Capacity (vanilla: 2000)": 10000,
  "Add Amount Of Water To Water Pumps": 1000,
  "Add Water To Water Pumps Every X Seconds": 5.0,
  "Water Purifier ML Capacity (vanilla: 5000)": 1000000,
  "Water Purifier (Powered) ML Capacity (vanilla: 5000)": 1000000,
  "Large WaterCatcher Stack Size (vanilla: 50000)": 250000,
  "Small WaterCatcher Stack Size (vanilla: 10000)": 50000,
  "Add Amount Of Water To Water Catchers": 1000.0,
  "Add Water To Water Catchers Every X Seconds": 5.0
}

The only way to fix it is to create a file in

oxide/data/WaterWorks.json

Because every time you restart the server.
Or reload the plugin. bug.

no idea what you're talking about ...

Merged post

Are you saying that the config resets to default each time the server restarts?

Exemple Water Barrel

"Water Barrel ML Capacity (vanilla: 20000)": 100000,

When you restart the server. Or /reload WaterWorks

Change to 20.000 in game

Config

"Water Barrel ML Capacity (vanilla: 20000)": 100000,
