I have been getting crashes under many different circumstances with medium and large galaxies, but not this one. However, the Devs told me that they have solved "the problem" (which makes it sound like it all traces back to a single code error) and it will be fixed in the "next patch" (which, with the announcements made today, makes me think it will be in the delivery that is expected out late next week or the week after).

I believe this was resolved with the Beta release. Please let me know if this issue is still present after updating to the latest version of Galactic Civilizations 3.

Thanks for the update! I talked to the developers about this issue and it has been added to the list.
