Hello, inspired by Gauntlet's Race Mod, I started to look at the soft code of the game and said to myself that I could do fun things on the game !
Unfortunately, after changing the soft code I got some errors that I can't solve:

FlavorText.xml(113,79): error: 

value 'CloseToSpecialVictory' not in enumeration

AIStarbaseGovernorDefs.xml(286,35): error: 

value 'Special' not in enumeration

FlavorText.xml(128,19): error: 

element 'FlavorTextOption' is not allowed for content model '(InternalName,FlavorTextOption+)'

Then I found this topic about modding limitations and wanted to know if it's topical or we have more freedom toward the modding, now?

For my mod I wanted to make a new star base, producing a new resource, and when reach a number of points, it unlock a new victory type.

Also aside of that, I wanted to know if it's possible to make planetary improvement taking not an hexagon but 7. (one hexagon around), for make a super improvement. The improvement picture can be bigger than the hexagon?

So for summary new :
-Victory
-Answer in diplomacy
-Trades
-Resource
-Starbase
-Movie
-StrategicIcon
-Improvement size
-Starbase Modules
-Alerts
-Design
-AI change
-Map parameters

Thanks you.
