When I create a EnderDragon pet. I crash, and if I rejoin I crash again after a second.

This is the crash report:

There is no error log in the console.
I tried making a pet other than ender dragon and that works. It's just the ender dragon.
Thanks.

The plugin version is: R: EchoPet v2.0.9 for CB 1.6.2-R1.0

Bukkit version is: git-Bukkit-1.5.2-R1.0-33-g50318a2-b2821jnks (MC: 1.6.2) (Implementing API version 1.6.2-R0.1-SNAPSHOT)

It might be my client. which makes no sense since I can spawn giants and my client won't crash and my computer is quite strong. I will reinstall the jar.

Never seen this before. Do you have any info or idea on what might be causing it?

A few questions:

• Do you have any texture packs installed?
• Does the normal EnderDragon work?
• If there are other players on the server, do they crash as well?

I did edit my comment to say it does work on another jar, although it looks like github doesn't want to know. -_-
and I did that the day I said that. 4 days ago

Ah. So can I close this, or is there something else I need to take a look at?
