The artifact from the abandoned rocket disappeared

After abandoning the rocket, the artifact I had been holding before abandonment disappeared.
It was still present immediately after the abandonment, but after the rocket debris landed on the asteroid and was dismantled, the artifact was gone.

One notable point is that there's another similar case where everything remained intact.
However, in that case, when dismantling the rocket debris, the liquid hydrogen and liquid oxygen were not stored in tanks but instead dispersed into the air.
