I was wondering what will happen to minehut servers once the 1.17 update is released. Will the worlds be updated to 1.17? Or will they be deleted? I don't really know how world generation works with the new caves and stuff, so if the worlds update, will it be corrupted? Well, corrupted, kinda messed up. For example, a new cave that just spawned in the middle of a build?
