Hmm, now I'm having another problem with area lights. If I create an object and convert it to an area light, it seems to behave both as a regular object, and as an area light simultaneously. Like, it is visible as a normal object (albeit without any texturing, but with shading from other lights), but it also emits light. I'd expect for it to be either glowing due to it emitting light, or for it to be completely invisible!
edit: and for some reason, setting its opacity to zero doesn't actually make it disappear!
