Causes for bug where starship is sent straight to orbit from ground?

I believe that I have been able to reproduce this behavior fairly consistently by landing close to and facing a large mineral deposit and then harvesting it. You don't need to be on it nor clipping through it (or any other terrain), and I am not sure if harvesting is required.

It may be that the launch thrusters move you forward into the terrain deformation (harvested deposit) and then the auto-altitude routine that prevents you from crashing into terrain uses your current (excessive) vertical acceleration to make the correction.

The work-around is to make sure you park so the deposit is not in your front-facing field of view.

I had this issue previously on every other take-off or so and it was extremely annoying. I'm not sure since when, 1.04 or 1.05, but it is fixed for me since then on PS4. It then only appeared one single time and that was when I landed too close to a pillar. I think the ship was even partially parked in that pillar. Then at take-off it got stuck and after a second jumped up into space.

So my guess on this is, this happens as some kind of safeguard to not get your spaceship stuck without being able to land or take off - and previously (at least for me) some parameters have been off and triggered that behavior too soon.

In case you got the latest update installed and still have this, then the only other guess I have is that it depends on the spaceship. I was grinding spaceship upgrades so was switching spaceships a lot. Maybe it only is an issue with the Rasamama you get in the beginning.

While the specific cause still remains unclear, the issue has been fixed, according to patch notes from the latest patch (1.07).

Fixed an issue that would cause your ship to be thrown in the sky at high speed when taking off (in rare cases could in turn lead to getting stuck).
