Citadels are absurdly rare

I have finally had another citadel spawn - my first since 0.2f dropped. I have been expanding the map a LONG way to try and find them. So far only iron and copper, no stone.

The video at the start shows the latest citadel to spawn , the second copper citadel in the fog was the last one I had found prior to 0.2f dropping. I had no shortage of corrupted nexuses prior to the fog glow being added.
