Conditions under which we have had successful games include.
3 humans using standard races on huge map. planets set to occasional, AI on gifted, minors abundant. We had a few crashes but were able to load back up and press onward.
2 player with custom races being used by humans and AI. Again we have occasional crashes but are able to restore.
During both occasions while in the lobby players reported the information being displayed about who is what race and at times team information is showing incorrectly. This has proven to only be a display issue for the lobby. Once loaded the saves are intact and players resume where we left off.
