So was Game.ChangePlayerEraScore function REMOVED?

I was calling this function in my latest mod, but the lua log keep saying the line "Game.ChangePlayerEraScore(playerID, amount)" as "function expected instead of nil"
I was playing on the GS ruleset, so it's no way I don't have the era score functions.
So did this function get removed? if so, is there another function to adjust player's era score?

 

I get the same error when I test for it, so apparently the function was removed from the "Game." methods.

It may have been removed completely or it may have been moved to a "Player:" method. But Firaxis don't send us documentation on what was removed or moved so all you can do is try alternative methods something like

 

So, after looking into the FireTuner, I found out the function has been changing into Game.GetEras():ChangePlayerEraScore(playerID, amount)
I don't know why they changed that, but fortunately we can found it out. The Lua Object table is outdated, hope someone can update it.

 

^this
Game.ChangePlayerEraScore() is now Game.GetEras():ChangePlayerEraScore()
