I just created my very first shulker farm, using RaysWorks newest design. After a couple days of this running without issue, my snow golem disappeared, and at this time, every shulker in the farm refused to open or agro the new snow golem, even though the main one was agro'd. I was able to bring the farm back to life by going to each "stuck" shulker so that it would agro me. After I did this enough, they eventually killed off each other, and all newly spawned shulkers are working as intended.
