Strange error using meteorhacks:cluster


I am using meteorhacks:cluster package and everything seems to be working fine (it is distributing requests accoss for servers) until I try and refresh the browser, then I get errors like this:

Zone already exported on window the object! zone.js?1438435695985:115
Uncaught RangeError: Maximum call stack size exceeded

Has anyone seen something like this before?
