I haven't tested all of the RTX worlds / packs yet, but out of the ones I've tested so far, Hilltop Lifestyle has sea lanterns that don't give off light, and ++Color, Light, and Shadow has the issues with the lava. I tested both in Neon District, and they both gave off light as they should. I've tried reinstalling GPU drivers and Minecraft, checking for updates, making a new world, and none of those fixed it. Everything used to work fine last time I played, so I think the issues just started in the new update.
