Eagerly downloaded 1.3 final, actually 1.3036. Then started a gigantic galaxy game which I had been waiting to play with 1.3 final. Played for past 5 hours or so. Now I find a version 1.3041.

Whats the difference?

Will I be okay to complete the gigantic game using 1.3036 or was there such a quick update because a major problem was found which will stop me completing my gigantic map game?

I have had no crashes or any other problems which have stopped me playing GC2 till the end since the 1.11 patch, this includes the 1.3 betas.
