Gron vs Toltayan.
First both races signes a Military Alliance, but at some point the war started...
The Toltayan expanded more fast, and removed the Gron colonies in several systems, but they
had not available minesweepers... then, were unable to finish the Gron.
In the other hand, the Gron had not colonized the Rock/Ice planets.... Don't think that's
exactly the 'Colony bug'. Simply they reached the max number of colony ship (5), and all
of them were Gas for the time when they got Rock/Ice.
After the Gron were able to create some planets, the problem with the Colony Ship finished... then the Toltayan had problems.
The Gron won at the turn 330.
