DRbObject causes other http-enabled modules to fail

One of my scripts initializes a DRb service/object to extend availability of local variables to other lich instances. When the script is complete, I stop the service and clear out all associated threads under before_dying. For some reason, after running the script, other scripts such as ;autovote stop working, returning something along these lines:

--- Lich: error: "druby://DESKTOP-REDACTED:REDACTED" is not a class/module

Redacted elements are computer name and port number. Not that it matters.

Is anyone aware of a workaround for this?
