+Subject: [PATCH] Properly destroy placed blocks on the end platform
+
+The craftbukkit provided implementation of LevelAccessor,
+BlockStateListPopulator, does not support destroyBlock calls, simply
+ignoring them.
+
+This causes the destroyBlock calls during the generation of the end
+platform to be lost. The patch moves the destroy calls and executes them
+on the actual world access.
