Been messing around with blood magic on the horizons pack for a bit, and I'm at the point where I need a demon blood shard to upgrade my orb. I set all the materials on the arcane pedestals, and my orb on the plinth and lightning started coming down and striking the pedestals, as what I assume is normal. Once the lightning strikes the center pedestal, there is a small explosion, and my minecraft window closes. On next log in, the demon that i had summoned is gone along with all my mats. I've done this a few times with the same results (cheating the materials in every time after the first, because I got cheated lol). I guess according to the crash log, I had summoned a Fallen Angel, but I never saw the thing, is there an issue with the monster itself, or is this the summoning thats doing it? Crash log is posted, thanks for your time guy =)
