It looks like you used my tutorial, which is neat. . I recommend to stop using autoborder entirely and work on the borders by hand to have the best results. Stalagmites are unable to become an actual thing unless they have a consistent flow of substance onto them, therefore having it above ground makes little sense. Try to use the mountain borders I used ( ID : 4456 ) Try to not have the mountain pieces ( The larger mountain rocks that connect to the mountain ) not be on top of each other, always have ground under all of the mountain pieces, don't have rocks / objects going onto the mountain pieces or any other sort of thing such as that, add ground debris by hand so that they go under the borders, and try to have it mainly rock soil. You still have a long way until you will become a great mapper but you are on the right track.
