# Preventions

## Vines max length

```yaml
preventions.vines-max-length: 16
```

Specifies the maximum length for growing vines. This helps to limit excessively long vine columns. By default, this value is set to 16, and it must be greater than 1.

## Fire spread

```yaml
preventions.enable-fire-spread: false
```

Controls the prevention of fire spread (this is a world game rule).
