According to this bug message, the meteor shower of death was due to a change in generation / Destruction routine defused:
Since the change of Gravitas Lobby in the last update, in particular the change from Neutronium Brick to Obsidian Brick, the meteor shower breaks through the lobby and destroys the underlying biomes before the breakthrough into space.
This is likely to happen whenever the lobby is placed by the world generator in such a way that the abyssalite frames are over-written and / or there are no reglith or mafic rock deposits over it.
Such a seed would be, for example, 2025793058.
The obsidian tiles are destroyed and the meteors can break through. After reloading the game, the tiles are automatically repaired automatically, so I assume the longer you play without recharging, the worse the destruction.
I uploaded the game, the destroyed part is not yet completely revealed.
Maybe it would be a solution to give the lobby a meteor resistance?
- Load savegame - Via debug tools, show complete map - See the destruction beneath the Gravitas Lobby
