Hello, your Plugin after updating Bukkit, he began to write a series of errors, which lead to long run the server to crash.

In particular Vault has problems with:

• Citizens
• DtlTraders
• stablemaster

[INFO] [dtlTraders] [INFO] Economy plugin not found! Disabling plugin
[SEVERE] [Citizens] Unable to load classes Rhino script - JavaScript scripts will only be Able to access CraftBukkit
[SEVERE] [stablemaster] Failed to load an economy plugin. Disabling ...

But I think it's a question of compatibility updates, and saw that all these plugins have been updated to 1.6.2

I hope you updated Vault since it's now become a vital plugins to play.
Thanks in advance.

Sounds like you don't have an Economy plugin installed. This is not an issue with Vault it is compatible with 1.6.2
