Mods, Steam Workshop, mod.io and TF2 compatibility

The October 22 desktop update fixes crashes from mods adding CSS files and aircraft with invalid metadata, improves validation and fixes mod ratings in Mod Hub. The publisher still distinguishes game faults from mod conflicts; preserve your mod list when reporting a crash.

An October 10 Steam reporter describes loaded saves freezing while audio continues; deselecting mods, reinstalling the game and clearing cache had not helped. After another player named Park & Ride, the reporter said deleting that mod resolved the fault. A second player reported improvement after disabling and uninstalling it.

This is a specific community recovery report. It does not prove a universal fix, explain why deselection failed or establish that required mod assets can safely be removed. Kingy has not reproduced same-save recovery or checked dependencies.

Preserve the original saves and record the installed build and mod collection before changing anything. A tested active-versus-deselected-versus-removed procedure is still pending; do not overwrite the original save or remove required dependencies on the strength of this report.

Stable 40420 fixes incorrect auto-activation of non-builtin mods, a construction-menu error caused by faulty mods, and a crash involving mods with dependencies in the staging area. It also lists several UI and rendering crash fixes. These are specific fixes, rather than a promise that every mod or crash is resolved.

The release history dates 40420 to Steam October 8 and Epic/GOG October 15; Steam stable has since advanced to 40425 on October 24. Console updates remain separate. Preserve the save and its required mod collection. Removing required assets or changing dependencies is not an established save-recovery procedure.

Urban Games describes a Mod Hub in the main menu where players browse, subscribe and receive updates. A mod.io web browser can also manage the collection. The current support FAQ says the same integrated library serves every launch platform.

The July dev blog still described Steam Workshop as undecided. The newer support FAQ supersedes that wording: Steam Workshop is not included because Urban Games chose a single cross-platform destination. Steam players use the integrated browser too.

The Curated Mods FAQ says Transport Fever 2 mods are not directly compatible. Authors can adapt them using updated tools and documentation. Basic conversion support does not turn an untouched TF2 download into a TF3 mod.

Do not copy an old collection into a new save and assume its assets, scripts or dependencies will load. Check the mod author's TF3 release and platform support.

Modding is open to players outside the Curated Mods Program, and all mods are described as free to download. Curated mods are available on every platform; Urban Games says most other mods will be too. That wording does not guarantee every general mod on every console.

The FAQ retains manual downloads outside the in-game browser, while the dev blog explicitly discusses manual installation for PC and Mac. The checked sources do not provide a finished folder path, save-migration procedure or console sideload workflow. Those instructions need hands-on retail verification before publication.
