Well there's that and also the fact that Nergal was particularly messed up from all of the bugs that it had encountered over the last year. It was good in a way because the database was so corrupted that it would expose flaws in the code very quickly. OTOH, because it was so messed up playing there could be an even bigger exercise in frustration than on the other servers. So in the end we just decided to wipe it and let it start over under the current codebase.
