I forgot to point out that its inconsistent, so maybe the first or second tease works, but the third crashes the game.
The same thing happens when you smack him or wait it out so the siegwulfe gets the job done.
Ty for the hard work btw.
Thanks for the thoughtful response. It likely took a few rounds to crash because the issue was one of his attacks, and obviously what he does is a little random. Should have his attacks fixed now though.
