So lately we've been having an issue with disappearing mobs. Normally I would say its an issue with a plugin but I'm not entirely sure whats up with this. The reason why is because it ONLY happens with certain permission groups, once the mobs get so close to the player they immediately poof gone. Talk about Houdini! I came here to ask for help on troubleshooting this, Ive eliminated all permissions and went through every permission to ensure its not the issue. I may have missed something but I doubt it, I spent 2 days debugging this. Heres a list of the plugins we run. http://pastie.org/3384400 And heres my permissions currently (they are a bit messy due to me going through every perm we used to use and what we do use...) http://pastie.org/3384408 ANY HELP would be greatly appreciated.
