I wanted to try this mod but when I tried a custom game I could not find Willem van Oranje. Where is he ?
Sadly what Walt said, but you can enable the Dutch to be playable through the xml that takes care of that, they have some very nice flavor units (they even got a unique knight model!) and the East Indiaman as their UU, but they are nothing special besides some nice stuff and 3 leaders (Johan, Floris, Willem) I hope one day we will see more of them.
If you want to know more just look at their page on the civilopedia you can see their leaders, units and more.
See above, I need to have more info. I can start a custom game with leader switching perfectly fine.
Maybe I should just reinstall the game completely I might have messed some stuff between installations, thanks anyway.

It's funny how most of the errors I have ever gotten always fix with just reinstalling.
EDIT: Alright reinstalling (got the hotfix!) was enough, no more crashes and because of that, no more errors on my side anymore
Possible yes, fairly easy no. Mostly because I am a bad coder who didn't annotate specific changes; some earlier components are annotated much better in code because they weren't done by me.
Very well, I shall get into it then...
I was wondering Walter, are there any new things in your mind for the next update of RI?

things stilll in development?
