If you mean that this is a problem affecting you and your application you could just iterate over the streams while increasing offset slightly less than the limit:
offset: 0 limit: 100
offset: 80 limit: 100
offset: 160 limit: 100
offset: ...
while keeping each channel name in a set to discard duplicates. It is most likely using the next link that causes problems for you. If you just want to alert Twitch development staff I think a mail would be more appropriate.
