Grave Zombie spawns when clicking on Hologram
Plugin Version: 2.9
Spigot: git-Spigot-492a779-731e819 (MC: 1.15.1)
Configuration: config.yml
Problem: When I click on the Mini chest to open my grave, everything works as expected. However when I click on the Hologram to open my grave, a grave zombie is spawned before the grave is looted! This means that graves could be used as Zombie spawners.
