What role do Crisis events (like Crisis on Infinite Earths) play in the discrepancies between official DC cosmology and the Battle Wiki?

Crisis events are major continuity resets in DC Comics, often altering or completely rewriting the established cosmology. The Battle Wiki struggles to reconcile these changes, sometimes attempting to maintain older hierarchies or create convoluted explanations to fit new information. Official sources embrace the fluidity, while the Wiki often prioritizes a consistent, albeit potentially inaccurate, structure.
