Earthquakes on Homeworld

[DanielAnsell]

Two games in a row now, one Classic, one Shadows, my homeworld has been hit by an earthquake, and had its quality dropped 30 points, maybe more. Once this happens, despite the world quality raising back up to 100, and tax rates being set, the world never again provides revenue. Given that the homeworlds are the biggest single income source, this has financially crippled my efforts in both games.

Has anyone else experienced this, and is it just a matter of time till the planet starts pumping out money again, or is something else going on?

I build a terraforming facility. It seems to help.
