I just updated the Myst V and HexIsle ages on the Shard to the versions generated by Drizzle 30 (Todelmer and CatfishCanyon had some slight changes). Since everyone needs to have the same versions of those ages, this means you need to re-convert those ages using the latest version of Drizzle if you want to visit them on the Shard.
Check the Converting Ages for the Shard topic for more information.
