While looking at the starmap, I think it's because the startmap is sort-of a surface and panning it triggers empty chunk generation?

The mod Better Asteroid Mining (1.0.1) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event Better_Asteroid_Mining::on_chunk_generated (ID 12)
__Better_Asteroid_Mining__/control.lua:22: attempt to index a nil value
stack traceback:
    __Better_Asteroid_Mining__/control.lua:22: in function <__Better_Asteroid_Mining__/control.lua:17>

Thank you for the report. It's been fixed!

I can add another error. I added the mod during an already running playthrough

Error while running event Better_Asteroid_Mining::on_configuration_changed
Better_Asteroid_Mining/control.lua:44: attempt to index global 'event' (a nil value)
stack traceback:
Better_Asteroid_Mining/control.lua:44: in function <Better_Asteroid_Mining/control.lua:39>

Stupid mistake on my part. Fixed!
