[R&F] Multiple DLC-specific dep files in a mod - does it work?

[Sejick]

I made a mod on the Steam Workshop (Capture Unique Improvements) where I wanted to redefine the artdefs for a number of bugged DLC improvements. Because the improvements are from different DLC, there need to be different sets of RequiredGameArtIDs in the dep files for each DLC source. I added four dep files with each looking something like:

    <RequiredGameArtIDs>
        <Element>
            <name text="DLC4"/>
            <id text="d5642886-43d5-4ce9-9465-3a47b5c70096"/>
        </Element>
    </RequiredGameArtIDs>
    <SystemDependencies>
        <Element>
            <ConsumerName text="Landmarks"/>
            <ArtDefDependencyPaths>
                <Element text="Landmarks_DLC4.artdef"/>
            </ArtDefDependencyPaths>
        </Element>
    </SystemDependencies>

This works perfectly in my own game, but other users have reported that the bugged improvements are not fixed in their games. I previously tried using only one dep file and added/removed all RequiredGameArtIDs from it, but that did not work either.

Am I doing something wrong? Is there a better way to do this? Any help is appreciated, thanks!
