Probably Stolen Mods: Demo Mods Now, Workshop at Launch

The developer's October 21 preview lists "Steam Workshop support + modding API + mod localization support" among the 1.0 features. With the Workshop, mods for the full game get an official place to be published and installed through Steam.

The Workshop does not exist for the Demo. Until October 28, mods are installed manually.

On August 30, the developer replied to a Steam discussion titled "Mod Support?". They confirmed that community mods already existed for the playtest and that mod support was planned for the full game. The October preview then named the Workshop and modding API.

The same preview adds a warning: mods made for the Demo will likely not be compatible with the main game. Plan to reinstall from the Workshop after launch.

Community references document mod projects for the Demo along with the builds they support. One example is the Real-Time Shop mod on Nexus Mods. Its files page labels versions for specific Demo builds, including Demo 049 and 050.

The current file, version 1.0.1, is labelled for Windows Demo 050rev5-L. That shows how closely mods are tied to a build. A mod for 049 may not work on 050.

Before you install anything, check the mod author's supported game build and loader version. Compare it with the build you are running. If they do not match, wait for an update.

Do not assume every DLL uses the same loader version. Each mod's author decides its requirements.

Back up your save files before adding any mod. A mod can change how items and machines behave, and a broken save is hard to recover. A backup costs nothing.

Update 049 added a Discover button on the load screen that finds manually added saves. That can help when restoring a backup.

Some Demo mods use MelonLoader. Follow the loader's official setup instructions rather than a third-party installer. The MelonLoader documentation specifies the Mods and Plugins folders and where the log file is written.

Ordinary mod assemblies go in the game's Mods folder. Always follow the individual mod author's instructions if they differ. We did not install or run any mod during our research.

Install mods one by one. Launch the game after each and check the loader log. If something breaks, you will know which mod caused it.

When a mod fails, remove it and restore your backup. Report the problem to the mod author with your build number.

We found a result promoting a third-party installer for a mod. It did not document compatibility or an installation procedure, so we excluded it. Treat installer tools that bundle mods with suspicion.

Download mods from the author's own page, such as their Nexus Mods files tab. After launch, prefer the Steam Workshop.

The Demo will be removed when 1.0 releases. Demo mods will likely not carry over. If you depend on a mod, expect to wait for its author to update it for 1.0 or publish it on the Workshop.

Demo saves are compatible with 1.0, but the developer recommends starting a new game. That is doubly wise with a modded save.

Does the mod's supported build match yours? Is the right loader version installed? Did you back up your save?

Is the mod in the Mods folder, and what does the loader log say? Answering those four questions solves most problems.

Community references point to Nexus Mods as one place where Demo mods are published. The Real-Time Shop files page shows the build each version supports. Read that label before you download.

Some community sites also document mod projects and their compatible builds. Use them to discover mods, then check the author's own page for the current version. The author's requirements always come first.

The Workshop will make installing mods a subscription in Steam rather than a manual copy. The developer also lists a modding API, which gives mod authors an official way to extend the game. Mod localization support is part of the same announcement.

Exactly how the Workshop and API work will only be clear once 1.0 is out. We will update this guide with release-build details. Until then, treat specific Workshop features as unconfirmed.

Does Probably Stolen support mods? Community mods exist for the Demo, and Steam Workshop support plus a modding API are announced for 1.0.

Will my Demo mods work in the full game? Probably not. The developer says mods made for the Demo will likely not be compatible with the main game.

Where do mods go? For MelonLoader mods, ordinary mod assemblies go in the game's Mods folder. Follow each author's instructions.

Is modding safe for my save? Back up before installing anything. Add one mod at a time and check the loader log.

We searched YouTube for mod installation tutorials on October 25 and found no verified English video with clear, accessible instructions. We did not include one rather than recommend an unreliable guide. The primary documentation linked in the sources is the better reference.
