I was searching for several different creatu, different colours and whatnot. Just before I last posted, I was searching in Rancher Shops, for a skaldyr, color sepia, no effects, not mutated. I use Mozilla Firefox 24.0 - it's the latest update as of this morning, and don't use any addons for it.
In fact, I just did it again, exactly as I've been doing it, and screen-capped the search page before hitting the 'query search' button, then screen-capped the results page. Going to try to post the images here for you:
This is the way I've used the search for a long time, only difference being that I'm following the advice given a bit earlier in the thread, and specifying "rancher shops" rather than leaving it to search everywhere for the creatu. To be honest, I'd love for it to be something I'm doing wrong, so I can just say 'boy was that dumb or what?', rather than have it be something wrong with the site.
