Rockets keep bouncing up when mining.

[Georgegad]

My rockets have landed safely on Minimus and I am trying to mine to refuel them.

They work fine and were mining and slowly refuling so I went on with the game but now whenever I go back to them they suddenly bounce upwards.

It looks almost like the mining shaft is pushing out of the ground and throwing the ship upwards.

I have made two diferent spacehips and they both do it.

What am I doing wrong and how do I fix it?

It sounds like you're not doing anything wrong, but instead encountering a common bug in the current version of the game. We hope it will be fixed in the next one.

One thing to check that might not be related to the bug...

The mining drill model has three parts that descend when it's deployed. The bottom two are the bottom shaft with the drilling head and the telescoping drill shaft above that. Both do not have colliders and can freely enter the ground. The next part up - it's mostly yellow and it cantilevers out from the craft - does have a collider.

So, make sure that the drill is mounted high enough that the arm that swings out doesn't touch the surface.
