Just to be clear, are you saying that when you go to your profile page, the sublemmys that you have ‘subscription pending’ for do not show up there??

The other thing to note with this bug, at least in my experience and what I have seen, even if it shows pending it will still show up in your ‘Subscribed’ feed. So while visually it is inaccurate, it seems to actually function properly. To be seen if the upgrade to 0.18.1 has any effect.
