Hello my friends, I have two major issues with HV's. First one I had stopped responding altogether. Just suddenly sunk the the ground and would not lift up. This one had the beginner hover engines (no thrusters required) Then spawned new HV (with thrusters) and that worked for a few minutes then did almost the same thing, although the new one moves very very slowly. It's almost as if the hover engines became completely disabled on both craft. Weight/Volume is turned OFF (I rarely play with that setting turned on)
Were you going through the planet's seam that goes north to south because that is when I usually get that issue but it corrects itself after a brief time but you have to have a bit of momentum. Even SVs stall on that as well but you are flying so you get over the problem area. It has something to do with the game trying to triangulate where you are compared to the map I think since technically you go "off the map" once you hit that seam. I have had that issue on 1.7 as well occasionally.
I actually had this same issue last night. My HV just dropped straight down--as I made a save file, iirc. I absolutely wasn't at the border. I wasn't even moving. I was in the process of dismantling the Abandoned Vessel Yard. The HV pads sank into the top blocks of the building, that it had been hovering over. I only was able to extract it by multi-tooling out the blocks (and then it was obvious it was sunk into the blocks). So the bug appears to be at some random point, the HV just drops and the pads sink into whatever surface is below them (if it's the ground, you would have to dig it up to free the pads).
