Please excuse if this question has alredy been asked... I'd never find it if it was here anyway...this place is so big. I've tried to create two new units... rebel and militia. these are supposed to be ground units with hidden nationality The rebel is ADM 3.1.1 and upgrades to militia 5.4.1. The problem I have is that the unit abilities box won't let me select both foot unit and hidden nationality. I click foot unit and scroll down to click hidden nationality, but when I do, it removes the highlight from foot unit.
In the civpedia entry field it took a couple of game crashes for me to realize I needed something there so I simply used PRTO_Longbowman and PRTO_Guerilla for these. At this point I did get to build rebel without having the game crash, but with no hidden nationality. I eventually quit this game because i still couldn't use rebels to kill AI trespassers without declaring war. I'm not good with computers and if I have to edit some file to do this I may as well forget it because I'm guaranteed to screw it up. I mean- I'm not trying to add new icons or civilopedia entries... I'm perfectly happy with the longbowman and guerilla icons and entries as long as the game can still run. Can anybody help me. Thanks in advance.

Ahem, press + hold ctrl and then you can choose different abilities. That is pretty much the same way you handle files in win explorer etc.
