I'm really enjoying the game so far! Thanks to everyone who worked so hard on it! However I am currently struggling to delete a habitat barrier. I can delete individual sections by clicking on them and pressing the delete key (as long as I am not in barrier edit mode) but I cannot work out how to delete larger sections or whole barriers. I assumed it would involve selecting the whole barrier in barrier edit mode and pressing delete but this does not work. I have also tried the normal multi-select tool which does not work either. Any advice? Thanks
