Hi! I'm playing on a Nook HD that has a micro SD card which turns it into a full-fledged Android. I just looked again and there isn't any check marks. I remember that after I bought the double food and double tech points while playing my first tribe, there were green check marks but not with this second tribe. Instead I see the 99 cents listed but if I try to buy it, it tells me I already have it.

How can you tell while actually playing? I know that my Master Farmers only add 7 food points for each basket of food they harvest from the crops and that my trainee and adept only add three food or four points for each basket.

I can't figure out a way to compare the differences between the levels of researchers.

Edited to add: Orange check mark? Not green? My memory is slipping, lol! Well, there definitely was a check mark after I bought them but I guess I can't remember the color.
