We are running the latest Spigot 1.9.4 release. We are using Multiverse for multiple worlds. We have WorldGuard as well. We have created a second End world that we use for a space theme, the dark sky without a moon is the primary reason. This worked fine in 1.8, but in 1.9 we cannot get the dragon to stop respawning with every restart. I've managed to disable block damage from the dragon (I think), but cannot figure out how the hell to get the dragon to stop respawning in this world. I've tried disabling all mob spawning, I've put the world on Peaceful, etc. Nothing works. Any ideas? Thanks in advance, all.
