Illegal and Rare Soul Sand Valley

This all happened without a stronghold or other rare cave structure: Fastion generated with 33 block gap, identical variant merge of two fossils generated twice, a giant crimson fungus generated in lava, a fossil had a structure collision with a fortress, fossils left into the nether wastes, one of the fossils got partially destroyed by a basalt pillar and more! Tell me if this is the rarest soul sand valley. Spectator recommended for exploration.
