Why did the patch change citadel locations of citadels already discovered?

I'm getting really frustrated with the citadel experience. I've cleared hundreds of maps doing all kinds of mechanics, and I'm like 8 screens away from the starting area now. I've only ever found 1 red beam in the fog for a citadel, and it was a few days before the patch.

I decided to wait and not go to this citadel until the patch, because of the talk about how citadels will spawn in clusters more often. But what happened? The patch removed the citadel I had found. The beam is gone. Now, I'm back to having found none and having no beams of light anywhere in the fog on my map.

The RNG here is just atrocious and makes me feel like I'm completely wasting my time. Why is it this bad?
