I’m sure I’ve played s3-7 in hard mode already as I’m now playing level 8
10 stages for 3 coins each = 30.
And it isn’t possible to play any hard stage if normal is done like in S2. You’ll have to play them consecutively.
Province 7 just released yesterday and it shows that you only played the normal levels as you got 30/80 coins. And unless you play all the hard mode levels in province 7 you cannot play the hard modes in province 8. So not a bug.
A blonde moment there.
Mod please close. @zephyr1
