Hello,
I've played through this mod several times, and I recently reinstalled it using 7th heaven with the "hardcore" gameplay mod setting (which I was led to believe was equivalent to installing this the old-fashioned way.)
Everything SEEMED to be fine - I fought the extra boss in Shinra tower (locke, venus, theo) and the other bosses were as hard as I remembered them, but when I got to Cloud's story in Kalm, I was not able to control Sephiroth during the fight with the green dragon, and he auto-killed it in a single crit. That's not how I remember that sequence going. Is something wrong with my copy of the mod? Is the 7th heaven version not actually the correct version?
