Keep the three records separate
| Record | What it helps you track |
|---|---|
| Collection | Which items someone grouped together |
| Dependencies | Which additional items or components are required |
| Local configuration | Which versions and settings your game actually uses |
Workshop behavior depends on the game’s implementation. Use Valve’s developer documentation to understand the platform role, then the game and item documentation for the applicable workflow. Steam Workshop implementation guide ↗
Why a list is not a snapshot
Saving an item ID identifies content; it does not by itself preserve the exact files you used. An item update, removal or changed requirement can leave an old list insufficient to recreate a session.
For a reproducible record, keep the game build, item IDs, observation date, stated dependencies and relevant configuration together. Where versions cannot be identified, mark that limit explicitly instead of claiming a frozen modpack.
Load order is a game-specific question
Do not assume that the order in a collection is the order in which the game loads content. Find the game’s documented loading behavior and the mod authors’ compatibility guidance. Conflicting instructions deserve investigation before you change a working setup.
A dependency list is necessary context, but it is not a compatibility test. Two items can each have their requirements satisfied and still conflict with one another. A useful recommendation must describe the set that was actually tested.
Before a bulk subscription change
Record the current setup and use the game’s supported backup guidance for valuable saves. Read the exact current interface before using a bulk operation: “add” and “replace” should not be assumed to have the same effect. This guide has not tested those controls.
We provide no universal bulk-removal sequence. If a set stops working, use the four-state investigation and preserve the evidence before making more changes.
Workshop versioning exists—but it is optional
Valve documents branch-aware item versioning. The game publisher must enable and organize the feature; creators or upload tools supply supported-version metadata. This can let Steam deliver an item version appropriate to a game branch. Valve: Workshop item versioning ↗
It is not a universal rollback switch. Missing version ranges may be treated as unrestricted by the system, which is not a compatibility test. Before relying on the feature, establish that the particular game and item actually use it. We have not tested an adopting game or a branch switch.
