Have been really wanting to have custom structures spawn in the Otherside but from testing with this plugin it seems when attempting to get structures to spawn they simply don't (my guess is it has something to do with how the otherside copies the blocks from the main world which makes sense as to why they wouldn't spawn lol). Would be really cool to have proper support for this since it would allow people to generate structures specific to the otherside.
