The last 2 episodes of the first half of Mushishi Zokushou were delayed due to production issues and later compiled as a sort of TV Special that aired on August 20. Apparently they are
not counting the special in the episodes numbering since the next episode will be ep.11, so I've edited the entry accordingly.
Not sure if this warrants creating a product entry for the special since it was originally planned to be part of the main series, and we would only ever link it to this.
