Suitor not following pathnodes.

[The chaser]

I think it's trying to say that the path from the path nodes must be the simplier as possible, so the monster makes a 90º change. Not really sure, though.

Think in a monster as a retarded, that helps. Mark them the things very easy so they don't get silly.

I know, it's a weird way to call them retarded, but dealing with them as these makes a pattern to work with.
