Retrieving cisco router config changes hostname!

Tonight we had a minor disaster. I set up OpUtils to copy some of our router configs, which had hostnames like this:

hostname router1.site1
hostname router1.site2

etc.

Well, OpUtils CHANGED THE HOSTNAMES when retrieving the configuration, dropping the suffix qualifier. As a result, a technician didn't realize he was in the wrong router and screwed up a configuration. I've verified the behavior in several tests. It also changes the domain name, prepending the suffix it stole from the host name (e.g., domain acme.com becomes server1.acme.com).

I must disable this behavior immediately. OpUtils should NEVER alter a router configuration while making a backup! This is unthinkable, and terrible IT practice. The router config must be left alone unless the OpUtils user explicitly orders a change. How do I disable this?
