Assets referenced by prefabs in the resource folder

If an asset outside the Resources folder is referenced by a prefab inside the resource folder, where does the asset get included at build time?

It seems like there is potential for the asset to get included twice if it is referenced from a level in addition to the prefab in the Resources folder, as the Resources asset gets pulled into it’s own blob.

Anybody know how this works?

Assets only get included once in the build, independent of how many times they are referenced as an asset can only be once in the player.

Exception is if you create Asset Bundles, in which case it can end in multiple bundles.
