[Bug] Random Game Crash In Area Under Base

[Haithere23]

Is there an existing issue for this?

• [X] I have searched the existing issues

Observed behaviour

While underground in the caves around my base in particular, I randomly crash. It is almost always in a different area (in the same few chunks) and happens inconsistently whenever I go into the cave system.

Expected behaviour

No crash under my base

Steps to reproduce

The actions I have performed directly before the crash have been:

• Using a builder's wand on a bunch of stone in the cave
• Casting thunderbolt at a wall towards a bend in the cave
• Digging with a fluxbore in the cave
• Walking through the cave

I don't know how one would reproduce this though as it is localized to one area (as far as I can see) and my actions don't have any connection when I crash.
