# PROP_PRESET_UNKNOWN

The rule preset the file names is not one Forge has.

## What happened

The `prop` attribute names a rule preset that is not in this version of Forge. When a preset with a close name exists, the message suggests it.

## What to do

Correct the name, or remove `prop` and set the rules yourself.

## Example

```text
strategy.py, line 7: my_firm_100k is not a rule preset Forge has. [PROP_PRESET_UNKNOWN]
```

The wording of the message depends on your file, and the code does not. An error stops the file from loading.
