So I just realized in the middle of the night that I skipped a key step in making a transparent .png: saving it as a transparent .png, without flattening it. In my defense it was 6 in the morning and I'm used to flattening the image before saving. I'm sure it's too late at this point to really matter, but I knew I'd be unable to get back to sleep until I fixed it. lol.
