on the skylands generation. I have noticed that a lot of structures do not generate. Including very important ones.. like strongholds and villages. not sure if that's just a height generation setting or if you decided to remove most structures from generating.

Please provide more information. Can you provide:

• MC and mod version
• Biome type
• World seed, if possible

The Skylands world type does not restrict structure generation in any way, if a particular biome has a structure, then it will try to generate it.
