java.lang.IllegalStateException: Unknown org.bukkit.craftbukkit.v1_7_R1.chunkio.QueuedChunk@ceff2174

What steps will reproduce the problem?
1. Start the server
2. Walk around or /kill

What is the expected output? What do you see instead?
The server will be successful at sending me packets for chunks and I will be able to play on the server without (or with less) lag.

What version of the product are you using?
Latest downloaded version.

Do you have an error log of what happened?

Please provide any additional information below.
I run a spigot server with these plugins:
Flow, RealArrows, RealWeather, RealisticTNT, zombieKill, WorldEdit, Reforestation, VelocityFall, BookShelf, BKCommonLib, TerrainControl, MehGravity, Bloodshed, BloodOnDeath, MorePlayerModels2, RealCompass, AsyncWorldEdit, NoLagg

None of those plugins (as far as I know) do anything with any type of weird chunk loading except TerrainControl. I removed all defualt 'terrains' from my server, including Desert, Extreme Hills, etc and replaced them with downloaded biomes from the internet.

I just tried again and used /kill to kill myself. Now I cannot respawn.

+1. I have the same problem. Server crashed when I started to move after entering the command '/nolagg monitor' (translate dot google dot com) \n Server log (craftbukkit version and plugins inside) - http://pastebin.com/ZqH7nEvw \n Crash report - http://pastebin.com/SapdGbYS

I too have the same issue. Once I disabled NoLagg, the issue was gone. I do have BKCommonLib and ProtocolLib, and those function fine. Here's my crash report. http://pastebin.com/D202VtaP And this is the full report of what occurs after I begin to move and immediately before the server begins stopping itself http://pastebin.com/mPcDbYcK

I'm getting this error too when using the /warp command.
