Looks like Kazam is onto something.

Yep, I had already done the shift-F5, cleared cache manually through options and yes, I do have an adblocker, but R'osity is one of the few sites that I allow because the ads aren't intrusive like some other sites (Youtube, what?)

I was going to try IE, like Kazam did, but it likes to hang randomly... even though I NEVER use it, so I couldn't test it on there.

I have a feeling by the time there's a fix, I'll have missed the huge sale.
