+Subject: [PATCH] Optimize NavigationListener
+
+I believe Mojang intended to call the NavigationListener Block Update
+method anytime a block is changed, but accidently added it for every
+block physics event instead.
+
+This code is massively ineffecient, and physics is so super hot, it
+destroys server performance.
+
+This patch moves the block update call to setTypeAndData instead of
+on Physics.
