Please note that version 2.0.0 is no longer compatible with the datapack map. to check compatibility, you can still use the older versions to check compatibility with other pack by donwloading them and adding to the datapack map with **"open Pack or Mod"**, tho i strongly recommend actually playing with 2.0.0+ for better performance. If Oceanus doesn't seem to be working, try changing the load order of the pack, it should generally be at the bottom of the list.
