So do I.I always thought the purple hexes would show which hexes are most likely expanded to by the cultural expansion? Could you clarify what kind of bug it is? A graphical glitch?
But it need not be one purple hex if we have wait many turns for cultural expansion. There can be more candidates at the beginning.There is supposed to be one purple hex, which shows which tile will be expanded to next - it is not random. At least, that is what we have been told
It was also said that there will be possible to select the direction of expansions. May by by working nearby hexes.
