Hi Luke, this is a problem with blueprints that contain water. It's a game setting that we can't change. Blueprints will only align with pre-calculated water levels hence the jumping. There's 2 solutions, either accepting it'll be slightly raised above ground level, or alternatively place the habitat, delete the water, re-save as a new habitat and then it'll align smoothly to place, then add the water back in

I'm struggling to place this as it doesn't allow me to smoothly adjust the height just jumps between set heights and when i get it as close as possible it says terrain modification failed, do you have any tips on how i can get it to work properly? Thanks
