Yes, I know you don't want spoilers as was mentioned in your earlier post. So, to not give you any, the only thing that I can say to help is to nudge your adept doctors back over to the plants and make them study. Also, if you have one that is more adept than the other, when someone does become sick; quick move the doc over to the sick one for healing. Other than real spoilers, I don't know what other ideas to give you.

Good Luck.
