I just tested again with the latest SS version with Dynamo as discussed here: http://www.minecraftforum.net/forum...ally-spawning-seed-specific-structures?page=8

Dynamo creates spawners that spawn "minotaurs", "Spider Jockeys" (cave spiders riding normal spiders), "Frost Blaze" (a 'cold' version of Blaze) and other very cool, unique monsters. Unfortunately, it looks like SilkSpawners strips the EBT data so those revert to ordinary Zombie Pigmen, Skeletons, Blaze, and so on. Would it be possible to please see if the SilkSpawners plugin will preserve the unique data attached to the spawner?
