Since it happened to me twice now, I thought this should be mentioned:

In both cases, an AI player who was dominating at the time and should have won by conquest with no trouble, reduced all his expenditures in the budget to zero (except ship and colony maintenance). From then on it stayed that way for years, until the player was eliminated. Reloading the game didn't fix this. How can I stop to AI from committing suicide like that?

In one case, this happened to the Drengin, in another, to the Korx
