-Subject: [PATCH] Fix Massive Memory Leak
-
-Pathfinder objects are storing references to ChunkCache's, and never cleaning up.
-
-These ChunkCache's then leak other entity objects. Those entity objects then have leaks to their
-own chunk cache. A recursive problem....
-
-Clean up the ChunkCache reference after it is done being used.
