I just performed a number of channel follows requests with limit of 100. Got 100 back everytime with the exception of the last request which topped off the follower count. Additionally, the follower count had changed in the time I was fetching all of the followers due to new followers. Perhaps one of these is causing your problem?
The problem occurs when I am requesting the followers of the streamer deraphin. No other user is affected (afaik).
I am continuously getting two followers less than the total number: 2,682 instead of 2,684
This happens all the time by every request. I have tested this today and four days ago.
So this is not a problem of changing followers while requesting.
Additionally, I am not using the offset at all. I am using only the cursor.
