I'm not sure if this counts as a dead link, but "tsubasa15_c112_19.png" seems to be corrupted in the DDL for "tsubasa15_c112_BWYS.zip". However the IRC complete volume 15 is fine.
As on that note as well, there seems to be a discrepancy between the DDL and IRC c109 is listed under v15 in DDL, but not in the IRC v15 instead its in the IRC v14.
And the DDL says there are omake for v12-15, but only available for IRC, yet i cant seem to find them on the botlisting.
But thanks for all your hard work, keep it up
