I'm trying to replace CarriageSystemScript.
Placing the compiled script under data/scripts works great.

But getting it to work for users of the Steam Workshop isn't working as good as I had hoped.
My first attempt was creating a bsa file that contains the script using Archive.exe
I then published the bsa and esp files to the workshop only to find out it doesn't work when installed through the workshop.
I have read about a workaround: add the bsa file to the list under "[Archive]" in skyrim.ini
Unfortunately this isn't a good solution for Steam users. They shouldn't have to make these kind of changes.

Then for my second attempt to get this to work, I made a copy of the script under a different name.
The Papyrus Manager in the Creation Kit tells me CarriageSystemScript is only used in DialogueCarriageSystem.
I've added my script to the dialogue, set all properties like they were for CarriageSystemScript and removed CarriageSystemScript from the dialogue.
I've let the Creation Kit generate a new esp en bsa file and uploaded it to the workshop again.
When I subscribe to the mod again, it still doesn't work.

Can someone help me out here?
