In clean
Release 2.2 it is
definitely possible to build Monasteries and Forts outside of your own cultural borders (if you have enough money of course).
(I did that in my last tests yesterday and usually built Monasteries and Forts like that in my games.)
And sorry, I am not analyzing any code anymore.
(As I said, I stopped modding. Currently I am not even playing Civ4Col anymore.)
I can only repeat:
In my last tests (yesterday, with clean Release 2.2) I did not find any bugs with Monasteries.
(I could build them outside of my cultural borders, they grew as expected, their features were working, ...)
Maybe there are some special cases though, which I oversaw since I do not use Monasteries like that in my style of playing.
Also, please be sure, that bugs reported are not caused by your modmod.
(Please do testing with
clean Release 2.2 when reporting bugs.)
Edit:
And yes, with "outside own cultural borders" I am talking about "neutral land".
It would be pretty strange, if the feature would allow building Forts (or Monasteries) in other nations territory.
Edit 2:
It is possible to build Forts and Monasteries "inside your own cultural borders" as well.
So that would also not be a bug. It is simply not the way I usually use those Improvments myself.
(I do consider Forts and Monasteries as "outposts in the wilderness".)
