When landing on a floating island from a corvette, it does not see the floating island as ground and so never leaves the sky diving animation.
You can land the corvette on the floating island too, no problem. But upon exiting the ship the (what I assume is) path tracing does not register the floating island as solid ground and you enter the sky dive mode again.
While it is fun to skate around the island once or twice on your belly, I would like to build my expedition 19 hut here please and thank you
