Little LUMI Model Launch, 1.0.1 freeze fix, then 1.1.0 OBS

Little LUMI Model shipped on Steam on 3 September 2026. The same calendar day, Studio LUMI posted hotfix 1.0.1: a Parade error dialog with two or more Lumis could appear and freeze the Settings window. On 4 September 2026 they posted 1.1.0: Broadcast mode so you can send Lumi to OBS from a new Settings tab. Those three notes are the public patch history this wiki will treat as fact until Steam news says otherwise.

• Patch 1.1.0 — Broadcast tab, Start Broadcast mode, she leaves the desktop for OBS.
• Hotfix 1.0.1 — what broke, who it hit, how to confirm the freeze fix.
• Launch notes — price, specs, languages, what 1.0 contained.

Official channels: Steam news, the store page, and discussions. This site is unofficial. We paraphrase notes; we do not invent patches.

How to take a patch

App ID 5075020. Let the Steam client update it. There is no in-pet store and no launcher besides the tray. Java is bundled, so a patch is not “download a new JRE.” After an update: fully quit from the tray, launch from Steam, restart once more if Workshop items are subscribed, then open Settings on purpose if you keep extra Lumis — that is the 1.0.1 test.

She walks offline. She needs Steam when you want the client to fetch a hotfix. Running her a week without Steam is how you miss 1.0.1 and then blame a frozen Settings window on “random Java.”

What 1.0.1 is not

Not a content drop. No seventh affection stage, no 65th behaviour, no new achievement names. It does not change the $3.99 price or the 20% intro that ends 17 September 2026. It does not enable Bongo, Garden, Pythagoras, or Window toss. Read the hotfix write-up if you already summoned extras; read launch notes if you have not bought the app. Do not delete AppData as a first step; use troubleshooting.

Steam labels 1.0.1 as a small update dated Thursday, 3 September 2026. One sentence: they fixed an error dialog during “Parade” with two or more Lumis, which also froze Settings. 1.1.0 is the next small update, dated Friday, 4 September 2026: Broadcast mode for OBS. Walkthrough: Broadcast mode.

Store copy already lists focus mode, alarms, favours, Workshop characters, and the four extras. Those shipped. Spend attention on first-week setup and Lumi Hub. If you stream, read 1.1.0 before you fight hide-on-fullscreen during a capture.

Patches come through Steam. Purchases go through Steam Support. Product mail on file: ai.init.alpha@gmail.com. Listed site: streamerlumi.com. Bug reports should include Windows 11 build, Lumi count, Parade yes/no, Settings open yes/no, Workshop items, whether 1.0.1 is installed, and whether the Broadcast tab is visible.

Bookmark this hub the way you bookmark any utility: boring until it is not. Launch day was busy; the hotfix was small; 1.1.0 answered the OBS request the next day.
