The error say, "it should not been happen, but it happened". Like that. So, I upload this crash log to you just in case if you are interested.
Edit: I can't describe properly because it just happen randomly and suddenly without any noticing. After loading the same game, it back to normal without this crash.
So instead I post a glitch that I can describe properly.
It somehow having a "goblin barbarian sound" when I kill this gltch/creature?
