I have a problem with special gold mine in combination with geologist skill Quality Gold Mineshaft.
Standard gold mine has production time 12:00.
Quality Gold Mineshaft is skill that find gold deposit, which can be mined faster.
Standard gold mine on deposit with Quality Gold Mineshaft has production time 6:00.
Special gold mine should be "A level 6 gold mine with a special look".
BUT when i have built special gold mine on deposit with Quality Gold Mineshaft, production time is still 12:00 instead of 6:00.
And this is BUG.
