No commands are working and I am getting this console spam:

I am using EssentialsX version 2.0.1-b461, Vault version 1.5.6-b49, and Hyperconomy version 0.975.7-SNAPSHOT

This is an issue in Vault's Essentials_Economy connector. I'll see if there's anything I can do, though. Which version of Essentials, Vault, and HyperConomy are you using?
