(Original comment: @Matt19901: Go)

Here i get this error in the console for the plugin using a dev build for 1.6.1:

Could you please provide the following information:

1. At the time of the error, were you attempting to use the /spawnvariant command?
2. If so, what mob were you trying to spawn and with which variants?
3. Does the error occur repeatedly or has it only occurred once?
4. What other plugins were you using at the time?
5. Does the error persist if you use the CraftBukkit 1.5.2-R1.0 build?

1. No
2. Same 1
3. Very rarely
4. [INFO] Plugins (50): MultiWorld, mcjobs, Rider, mcore, Vault, Parachute, PhatLoots, DisguiseCraft, OpenInv, Votifier, GemXP, MobArena, DoubleXP, SimpleVoteListener, Portals, WorldEdit, uHome, VanishNoPacket, ChatColors, PlayerHeads, PermissionsEx, ChatGuard, LogBlock, CreeperControl, Questioner, More-Mobs, Commandspy, MCPacks, ComPassionate, MobVariants, Nicknames, pvparena, FactionMobs, CraftBukkitUpToDate, AntiXRay, WarpMaster, Herochat, SignURLs, HeavySpleef, CommandBook, mcMMO, BOSEconomy, WorldGuard, Factions, Register, CompatNoCheatPlus, ChestShop, FactionsPlus, NoCheatPlus, MagicalSpells and MobHealth which is having it owns issues so i disabled it
5. Not that i have noticed

And the plugin still works

@Matt19901: Go

Did you disable or change any of the plugins when you switched from 1.6.1 back to 1.5.2?

@Hunter_X: Go

I disabled MobHealth and combat tag is on but isnt loading and i updated several of them

@Matt19901: Go

Does the error still occur if you temporarily disable all of the plugins except MobVariants (you may want to test this with a copy of your server files so you don't have to worry about losing the config settings for your other plugins in the live version), in either 1.6.1 or 1.5.2?

i think that mobhealth could be causing this maybe

Hi, has this been fixed yet? I am also getting an error. I don't use mobhealth like Matt but i use healthbar. We also use mcmmo which is interesting.

Caused by: java.lang.IllegalArgumentException: Health must be between 0 and 201.55125427246094

This pops up in varying numbers within the error messages.

At the time of the error, were you attempting to use the /spawnvariant command?

I have never used the /spawnvariant command and left it to spawn naturally.

Does the error occur repeatedly or has it only occurred once?

This happens very frequently on my live server - DOES NOT happen as the only plugin on a 1.6.2 local test environment.

What other plugins were you using at the time?

WorldBorder, bPermissions, DiscoArmo, neoPaintingSwitch, Vault, Backpack, MyHome, stables, bChatManager, Decapitation, OpenInv, BanManager, DailyLog, ProtocolLib, SimpleHug, Votifier, mcMMO, GAListener, Lift, QuickShop, WorldEdit, SignEditor, Simple-AutoSave, PvPTime, HealthBar, EchoPet, WorldGuard, ChatGames, Commandspy, IP-Check, AntiXRay, Lockette, MyWarp, MobHunting, Freeze, Essentials, Enjin Minecraft Plugin, Prism, Chairs, CompatNoCheatPlus, EssentialsChat, NoCheatPlus, EssentialsProtect, EssentialsSpawn, EssentialsGeoIP, VanishNoPacket, EssentialsAntiBuild, PreciousStones, CraftIRC

Does the error persist if you use the CraftBukkit 1.5.2-R1.0 build?

Not in a test environment - I'm unable to downgrade live and currently do not have a local backup of my live server.

I hope this is of help to you and if you request anymore information I'll be glad to help. I like this plugin and in game all appears to work regardless of the console errors.

As u can see

Caused by: java.lang.IllegalArgumentException: Health must be between 0 and 484.8799743652344

Something with Health!
