Mobs not spawning, making no sense whatsoever ...

Alright, so basically my issue is that mobs won't spawn. I've checked my plugins, and I've checked the settings for those plugins, and it seems as if they should be spawning just fine.
I'm currently using the latest dev build, #977

Mods in use:

• JSONAPI
• MyHome
• HeroicDeath
• MyWarp
• OpenInv
• WorldGuard
• mcbans
• BlastPick
• Permissions
• LocalShops
• BigBrother
• WorldEdit
• LazyRoad
• iConomy
• MinecraftViewer
• VanishNoPickup
• MultiInv
• ChatLog (custom plugin)
• AutoSave
• BuddyUp
• AssignPermissions
• MultiVerse
• HookShot
• Survival (custom plugin)
• DonationPackage (custom plugin)
• LWC
• Paid2Mine
• BanList (custom plugin)
• NoGod (custom plugin)
• MobArena
• NoCheat

The only plugins I could think of that modify anything with mobs are the following plugins: DonationPackage (only handles spawning), MultiVerse, and WorldGuard.
I've checked my MultiVerse Worlds.yml, and it appears that everything should be working just fine, however I may be wrong ...
This is my Worlds.yml:

I've looked into all the worldguard settings and it doesn't appear that there's anything that would cause the mobs to just not spawn.
In my server.properties, it appears that mobs and animals are on, pvp off. That shouldn't disable mobs, but I could be wrong

I would appreciate any help that I can get, I just don't understand what's happening here.

 

im having the exact same problem i hope somone will help us

 

Check your server properties and make sure monsters are on
