Um dom2 crashed with nagot gel fick or something

I was on turn 87 hit host, back round goes black, a dom2 screen comes up saying nagot fel gick or something like that. I clicked it a stat window of a fiend of darkness(fiend mictlan can summon right away) comes up and before I can read anything there dom2 crashes. I was playing tien chi SA patch 2.15 mac osx 10.28
