I had the crazy thing happen yesterday. While playing a game, all my units disappeared. I tried loading a new game and also a game in vanilla. Same thing. So, I uninstalled Civ IV Colonization, reinstalled plus the patch, then reinstalled Age of Discovery II. plus the update and Pirate file and it works fine now. I think I will wait till a final version of Futher Discovery is tested and debugged to reload it. I also down loaded the Blue Marble Graphics.......Looks fantastic. Wish list Items needed for Futher Discovery: 1. 2xRadius 2. Working Custom House (one Colony) 3. Abandon Colony (allows for removal of last colonist) 4. Gold w/Miner (include "gold rush" event like Fountain of Youth) 5. Plantations....(change Coffee to Cocoa/Coffee and upgrade Indigo to include Dye) 6. Slaves (need improved so European AI can use) 7. Reworked Pirates/Privateers........ improve ? 8. Create a New Building called "Military Academy": allowed only one per Civ in a selected colony and prequisite buildings are University & Arsenal. This allows for training of "Professional Soldiers". 9. New Colony wagon (wagon must be built and only this unit can build new colony) 10. Include Research/Science Profession along with tech tree 11. Remake Australia into British Canada and while vanilla English = "Original 13 Colonies" 12. Remake China into Brandenburg (pre Prussia German) 13. Add in Denmark and Sweden or make one new Civ called "Kalmar Union" 15. Make Petty Criminal to Indentured Servant to Free Colonist promotions like COl I. 16. Allow ships to be sold in Europe (privateer prizes) and all ships must have a crew (sailor) 17. Update Inuit Civ leader and include sound 18. Add one other native American Civ for North America "Algonkin" (Great Lakes Tribes) 19. Add in whaler profession and include secondary as Whale Oil (need Whales off shore) 20. Make non-military civilians to be captured instead of killed if caught outside colony.
