See the picture - the zombieman wants to go get the medkit so he's stuck in that place.

I'm sort of curious why the AI would use a separate "ooh, shiny!" algorithm to move toward a medkit instead of using regular ol' A*.

DoomRL's AIs don't do full A* searches; normal enemies especially can abandon the search fairly aggressively (which is happening in this case).  I believe this is mainly a speed consideration, as it is possible for many enemies to be on the level at once and running too many searches can slow things down.

Of course, it is possible to make up the speed difference in other ways (such as running searches less frequently), but I don't believe this is a high priority at the moment.  The current search parameters seem to get enemies where they're going most of the time.
