That ... makes sense.
LOL, I didn't know you guys were actually BEATING the boss.
I mean, were you guys cheating or something and maxing out your characters' stats? When I played through the game normally, I got one-shotted by Gawain at that point in the game.
As I said earlier, I didn't think you were ABLE to beat him, so the fact that you're getting a freeze or something makes sense from a dev's standpoint. However, I do think the dev probably should've made the boss invincible, rather than merely overpowered, so that something like this, however unlikely, wouldn't happen. Then again, it's basically a middle-finger to anyone who cheats, lol, so it's also a little amusing that it turns into an inadvertent anti-cheat method.
