# FAQ

> License, Folia, migration, performance claims, and common questions.

## License

### Do I need a license key?

Yes for paid builds. Set `license_key` in `config.yml`. Claim product id **`3TSPAWNER`** in Discord (`/claim 3TSPAWNER`), then paste the key. Verification always runs on startup — there is no config option to skip it.

### What if the license API is down?

With a previously successful verify cached, `license.grace_hours` (default `72`) can allow boot. Fresh installs without a valid key will not stay enabled when verification fails.

## Platforms

### Does 3TSpawner support Folia?

**Yes.** `folia-supported: true` and a region-safe scheduler facade. Paper, Purpur, and Folia are supported targets for `1.20.6`–`26.x` (Java 21+). Use `/3ts doctor` to confirm Folia detection on your host.

### Paper / Purpur versions?

Target **Java 21+** and Paper/Purpur from **1.20.6 through year-based 26.x**.

## Features

### Physical or virtual?

Both, plus **clusters**. Toggle each under `modes` in `config.yml`.

### Is the default shop vanilla-only?

Yes. Shipped `shop.yml` is vanilla physical + virtual listings. Custom, Mythic, Elite, and `provider: item` gens are opt-in.

### What is `3tspawner.autosell`?

A **5% sell payout bonus**. It does **not** automatically sell storage.

### Can I rename `/3ts`?

Yes — `commands.primary` and `aliases` in `config.yml`, then **full restart**.

### Why does migration say beta?

Migration tools (`/3ts migrate …`) are labeled **beta**. Always `/3ts backup create` before `apply`. Perfect imports depend on the source plugin.

## Performance

### Will it fix my lag?

It is designed to cut entity load via virtual/cluster production and lag-safety. Results vary with TPS, hardware, other plugins, and limits.

### What about the \~1.3% Spark figure?

That is a **showcase / demo** observation, not a warranty for every server. Treat it as marketing proof of a tuned demo, then measure your own Spark report.
