[Bug]Sorting and Offset do nothing for /reviews/ API

These API calls all return the same thing:

https://www.giantbomb.com/api/reviews/?api_key=<KEY>&sort=reviewer:asc&limit=2&offset=0&format=json
https://www.giantbomb.com/api/reviews/?api_key=<KEY>&sort=reviewer:desc&limit=2&offset=0&format=json
https://www.giantbomb.com/api/reviews/?api_key=<KEY>&sort=reviewer:desc&limit=2&offset=1&format=json

I'd imagine these to all give different results. Using the same set of parameters for /user_reviews/ seems to work. Is this a known issue?
