I have a custom interior cell with the music set to 'town' in the 'World Cells' tab. The problem is that on entering the cell ingame the music starts and plays for maybe 5 seconds and then fades out, leaving the cell quiet.

I cannot find what could be causing this. The music is the regular Skyrim music and the cell is set correctly. I did have a sound marker that played a sound at a specific time, but even with this removed I am still having the same problem. It is not just me, anyone else who uses the mod has this same issue in this particular interior cell.

Has anyone got any ideas what this could be?
