Trapped in hollow iceberg

[Skykid]

Help: I'm stuck.
While approaching a big iceberg, I was helpfully told that the iceberg was hollow, so I went to explore and used my laser cutter to open a hole and go inside. Once inside I collected an Ion cube and some minerals, and saved my game. When I came back to the game a few days later, the hole in the iceberg has frozen over, and I cant get out. My laser cutter cannot cut the hole open again, and i'm stuck. Any advice, or do I have to start over again?

If you manage to die you will get resurrected at the nearest base/your seatruck. So maybe if there is some water inside the iceberg you could simply drown in there.

If you don't care about achievements you can use the console.

In this case, the ghost command is probably the most applicable.
