The last test:
F:\Civ_4\Beyond the Sword\Mods\Caveman2Cosmos
I replace ALL files of \Caveman2Cosmos by
SVN 9036 H:\Civ4 C2C SVN (what is my SVN download folder), except folder .svn
So F:\Civ_4\Beyond the Sword\Mods\Caveman2Cosmos is absolute identically with the current SVN
Result: F1 not working
Then I renamed F:\Civ_4\Beyond the Sword\Mods\Caveman2Cosmos to F:\Civ_4\Beyond the Sword\Mods\new-Caveman2Cosmos
and extract the 2015' 7z package of F:\Civ_4\Beyond the Sword\Mods\Caveman2Cosmos which has last file dates October 23, 2015 and load an old game played past Christmas with this.
Result: F1 works fine
Then I delete that folder and renamed the "new-Caveman2Cosmos" back to Caveman2Cosmos.
Then load an old sav of 2014 made with V35 download version that time, and V36 could load it (while the sav of 2015 Christmas sav made with v35 svn does crash if I try to load it with V36). Also with this old sav of 2014 F1 did NOT work in V36, but with the v35
So, what may be the thing? I only can see that the problem is with v36
Or, what is my suspect, yours is running fine as you never made a total fresh installation of v36 but are carrying just the one(?) related file causing this of v35.
(btw, the sav made with v36 does crash with v35)
Edit:
I have stored in backup as a 7z the images with file date 2015-12-04 which is SVN V35 and SVN image of 2015-10-23 of V35, both w/o folder ".svn"

Edit 2
I'm just downloading the downoad version v36 of 23.Oct 2015 from the link here told.
As I Understand, as my filedate of the version I refer to is of 23.10.2015,, it is the 36 and not the 35.
and also that one you tell abone.
Now I will see, if that version works with F1 and do a total file comparision (by total commander compare file contents) to see what is the dfference.
