# `manifest.large_room_untested`: Rooms over 8 players are not simulated

A build check warning in the area "manifest.json". A warning: the game still publishes, but fix it when you can.

The build check runs on every game LobbyLab builds, and each problem it finds has a stable code, the exact message, the file and line when it names one, and a link to this page.

## What the check looks at

manifest.json describes the game: its slug, title, player counts, execution profile, join policy, subscriptions, smoke intents and settings. It is strict JSON with no unknown keys.

## How to fix it

The simulated match runs with up to 8 players. Test bigger rooms yourself.

Fix the field the message names. Player counts are 1 to 16, `subscriptions` includes `member.join_requested` and `session.start_requested`, and every smoke intent's `actorIndex` is below `minimumPlayers`.
