"Reached end of file" 3 times. What is this I don't even.

I was just attacking TT mobs in CH 15 and this happens. I then just tried chatting with someone in CH 8 or something and I still had the game close on me. Anyone know why this happened? I'm uninstalling and reinstalling the game regardless, but it wouldn't hurt to know the "why" behind this.

I think that is the channel crash hack that is going around, I saw some other people complaining of the same thing
that had an error code attached with the max meso number in it.
