Beams for Citadels and Corruption Fog Not Showing/Rendering

Sometimes in the fog I have seen some corruption areas, but then if I go back to look again where it was later it doesn't show. There's definitely a problem with how it renders. I tested this by marking where I knew I've seen corruption fog on a nearby revealed map (but corruption was not revealed yet). I check back again after reopening the atlas and then it doesn't show the corruption fog anymore.

I have still yet to see one beam for any citadels, so I have no idea which direction to target, but I would assume it is having the same rendering issues on the atlas as the corruption fog is. Last patch I was able to see several around my atlas in multiple directions with less explored.
