You need to allow relay override scripts via a setting, but other than that it should just work. Mine seems to works still at least.
Something has changed that has removed the counters by the familiars that needs counters for things like runaways, drops, etc. I don't think I've changed anything except for adding my fullness counter to my character pane, but removing it didn't seem to make the familiar counter appear again.
