Napoleon total war update? (500 MB)

Today i open steam.... and start downloading 500mb... what is that? I am alone?

Damn, just deinstalled it yesterday

I suppose it's a Steam update, not an NTW update

The last update I think was when they release those unit DLC. If you haven't played NTW (or run Steam online) since before the last update then it probably the update though I can' remember how big is the update size. Or if it's your NTW is being update then possibly some files somewhere got deleted and the game automatically redownloading the files.
