A number of years ago, I created a servitor with specific qualities that were beneficial at the time.

Because I did not put a time limit on the servitor ( I didn't know what I was doing back in the day) and it has been around for a long time, it has taken on a mind of its own and will not leave. It is causing a lot of problems and it needs to move on or disappear or do whatever it is they do when they go away.

Anyone had any luck with a problem like this? Advice?
