Limited Structures
Make structures generate only once (configurable)
About this Mod
With this mod every structure becomes unique since it prevents generation of more than one of each structure type per dimension.
Both the default limit and per-structure limits can be configured.
You can also blacklist mods and structures by their id in the config file, or turn on whitelist mode and limit only specified mods/structures.
