when trying to select a different "world" i am having to click several times and in some cases quite a bit, to pick a different world. I attached a video so you can see. When you click one of the asteroid images in the selection scroller it gets "stuck" and just randomizes the seed instead. Please see video 2019-07-26_19-32-21.mp4
Try to create a new world, do nothing else but click a new asteroid, move forward and backward through the menu trying to advance to the next asteroid type. You will need to click many times and you will see the seed counter increments when the asteroid is clicked instead of switching to it.
