I'm running into a NoMethodError originating from the .billingItem call in the SoftLayer::BareMetalServer.cancel! method. Code Snippet: `bm = SoftLayer::BareMetalServer.server_with_id(id, options = {}) bm.cancel!(:unneeded, '')` `c:/Ruby193/lib/ruby/gems/1.9.1/gems/softlayer_api-3.0.0/lib/softlayer/BareMetalServer.rb:53:in cancel!': undefined method billingItem' for #<SoftLayer::BareMetalServer:0x428a318, jhlintestbm> (NoMethodError)` Any input would be greatly appreciated, thanks!
