You may wish to add Dimension IDs from mods to Mariculture's Ocean Generation > Blacklisted Dimension IDs config setting. I and several of my friends have encountered a game-breaking crash that occurs when Mariculture attempts to add ocean decorations to certain third-party dimensions, such as Erebus. I have a list of all the Dimension IDs if you need them, otherwise they can be found in their related mod's config settings.
