I'm experiencing an odd problem. Today I started up my server and logged in, then proceeded to kill some mobs. A creeper blew me up and I returned to my death point to find that every non-passive mob had despawned, and none of them were respawning. I flew around for at least 5 minutes and did not see a single one. Reloading did not help, nor did logging out and back in. I completely restarted the server and the same thing occurred. Mobs spawn, I die, mobs disappear. Spawn eggs still work, they just don't spawn naturally anymore. WTF? I have these plugins: ChairCraft, CustomJoin, CensorIt, WorldEdit, SimpleFly, BlockBlocker, MoreExp, Vault, DeathNotifier, PermissionsEx, Multiverse-Core, LogBlock, MobBountyReloaded, PlayerStatus, NoSpawnEggs, BorderGuard, WolvesOnMeds, SimpleJail, ChestRestock, EndReset, iConomy, SafeCreeper, OpenInv, Newsletter, Lockette, Modifyworld, MonsterBox, MobDisguise, MoveCraft, RebuildPlugin, QuickWarp, CleanroomGenerator, Citizens, ChatManager, OtherDrops, MultiversePortals, iZone, Multiverse-Inventories, Sign Bank, Multiverse-NetherPortals, Warpz0r, ChestShop Also, in my server.properties, difficulty is on 1, spawn monsters is true. In my Multiverse files, each world is set to easy and spawn monsters is true. I just don't know what to say, this is very frustrating. I don't know if it's a new issue or has been going on without my noticing for ages. The reason I discovered it today is that I was testing my updated MobBountyReloaded and the MoreEXP plugin. But removing those plugins didn't fix the problem either. Maybe it's a Bukkit issue or something, but I JUST NEED SOME HELP!
