bad news. It didn't work.
I tried putting Adramalech and Manargarmr in the same folder, and they worked fine. So I'm guessing they kept the old one but changed how the script for the new release works.
when I run download asset, it only says
C:\ <directory>
Amaltheia 1301_harem-summon.json
and so on
C:\ <directory>
Press any key to continue ...
EDIT: actually I tried Adramalech from my backup files. when I open the .json from the game, it also has changed. so I assume the new files can't be used too now.
EDIT 2: I noticed the new files has the exact same content as the DMM files. so we're going to need a program that can grab the files and make the scenario like it's for DMM version
