Heya! I am a total newbie when it comes to modding and I created my first music addon pack with construction kit using just the vanilla Skyrim .esb and Update .esb. I added a few music files and included them in a few original playlists and saved the .esp. However, now it seems that if people play with Dawnguard DLC, the music mod somehow overwrites the DLC musics. I tried to remedy the situation by modifying the editor.ini and adding the Dawnguard.esb references and multiple masters and such required additions, then opened the construction kit by activating Dawnguard in addition to Skyrim and Update and saved my esp file again. Now I hope it works better with Dawnguard. However, after this change, I can't load the esp anymore if Dawnguard is not active (it doesn't work with pure vanilla Skyrim). My question is: Should I upload this updated Dawnguard version of the mod as a new version of the existing mod and just update the description so that 1.2 version requires Dawnguard and previous 1.1 version requires Vanilla? Then people should be able to download the previous version if they need to. But does this break the game for people who update the mod without realizing that they need Dawnguard as well? Is this the way to go with existing mods that need to support more DLCs than they originally do?
