I changed the way automatic conversions and deconversions work a while ago, and I think I may have been a little overzealous in some areas. It's something I've been meaning to revisit for a while now, but haven't had chance.
So while I can't speak to specific issues without seeing them in action (it's possible you've also found a
separate bug in the way followers are calculated), I'd say that it qualifies as a quasi-bug
I will try and see if I have some time to look into it in the near future.
