I have an industrial tesla coil set up and working properly, but I can't seem to get the loot collection. I placed it in the nether next to a blaze spawner to collect blazes. I placed the loot collector so that the beam was shining into the tesla coil, and placed a blaze rod in the filter slot of the loot collector. But while the tesla coil has killed many blazes, I've yet to get a blaze rod from the loot collector.
