There are some steem accounts, which I want to follow but something seems to be wrong with the execution of follow commands or follow/unfollow button displaying.
Example:
I want to follow steem accounts 
I click Follow button on
The command executes as I get following screen. Both accounts seemed to be followed by me now.
SteemWorld: ok
Steemd: ok
Everything seems to be working fine, but when I refresh the page in browser or revisit same accounts later on, it looks again like I'm not following the two featured users from this post.
Is there any particular reason for this or is it just some bug in the blockchain?
I don't know how the 2 users see this, but they probably get the message I started following them all over again (at least in Notifications section in Busy.org). And this must be pretty anoying to see, and I appologize to any such user for just wanting to follow them.

UPDATE 2
I just realized one thing, which might help 
It seems that if I follow many persons and try to follow newly somebody from the end of the alphabet, this doesn't properly show in follow/unfollow buttons. It looks like a time related issue in combination with number of people followed. Try to think in this direction, maybe there is something to it.
