Like the plugin - it's working just fine, save one thing: it's ignoring exclusions. It's going to my custom taxonomy/terms just fine, but I want it to exclude 2 categories (passed by variable, because in one instance, only one of them is excluded), but it's ignoring the excluded term ID. Even when I hard-code it in (instead of passing via variable) - the category that's NOT supposed to be in there is still in there.
