[bug] Destroying pirate starbase causing game freeze

Hello,

A civilization had a mining starbase which both exploited a red (mining) ressource and a precursor ressource (xeno archeology).   I had build a mining / archeology star base close enough to take possession of both when that mining starbase was destroyed.

When I too out the last world of that civilization, the mining starbase became a pirate starbase.  I destroyed it, thinking both ressources would then be claimed by my mining / archeology starbase and all it did was freeze the game.
