PaperMC/nms-patches/EntityHanging.patch
Stefan e1070b9fbb SPIGOT-206 Further checks and fixes for Hanging entities.
Adds an check for existing entities before selecting the location allowing
for hanging entities to be spawned in blocks where there already is an
hanging entity at the default rotation.
Fixes the CraftHanging setRotation function to use the new 1.8 logic.
