Forewarning: I didn't look at the scripts.
Does this happen to all calls or just some calls when going to the CSQ in question?
Either way, check which skills have been assigned to the CSQ and their competency level. Make sure the agents that are logged in for that CSQ have the skills associated with the CSQ and the minimum competency levels required.
If that all checks out, you're liking running into a bug.
