Making monster disappear

[CD Set]

I think this is part of the design. Not knowing when an enemy disappears also makes it hard to know when it will appear. There are a lot of randomly placed encounters too, I've heard.

I died in the prison once, and after "spawning" (in lack of a better term) the monster had disappeared. It appeared in a new location, walked away from me into a darkened corridor and before I knew it, ANOTHER monster had appeared in the hallway behind me, which kind of threw my perception off a bit. You can never really be sure when an enemy might or might not be where you think it is.
