Here is how to make an instant crash building if you want one to let you exit out of the game more quickly (if you are having really long exit times). Go into EDB.txt (export_descr_buildings.txt - you will need to use a text editing program - but for god's sake, save the file first as a backup in case you get something wrong), find the missles building complex and edit the first level. Give it one unit that your faction gets anywhere - and make it have a building condition (that is the part that causes the ctd - a unit with a building requirement).

Now, when you click on that building to view it, you will see your one unit. When you click on the unit - you get an instant ctd. This should work for all factions. Only replace the stuff you see here - from "practice_field requires.." to "...settlement_min village".

Code:
        practice_field requires factions { all, } and not hidden_resource not_here
        {
            capability
            {
		recruit "roman missile accensi" 0 requires factions { seleucid, } and not hidden_resource not_here and building_present_min_level government gov4
		recruit "eastern skirmisher cavalry mada nizak asabara" 0 requires factions { parthia, } and not hidden_resource not_here and building_present_min_level government gov4
		recruit "celtic skirmisher balroae" 0 requires factions { gauls, scythia, britons, } and not hidden_resource not_here and building_present_min_level government gov4

Just use it for quick exits. Also make sure you save your game before you exit of course, but also save your EDB file too before editing it like I said before. Heck, you don't even have to build them - just click on the building in the preview construction screen. That's why I made it so expensive - so no one exploits it. Maybe I can get them to put this in for future builds - with a "not" that just has to be removed or something to make it work.
