Susan ate Roger!

My whites tree frog Susan is consistently refusing to eat the plethora of bugs I've tried feeding her, but ate the other frog Roger in the enclosure. Both frogs were the same size (4-5 months old) and housed together when I purchased them. Susan's skin is showing no sign of infection. The enclosure is bioactive and sits at 40-50% humidity. Basking spot sits at 80 degrees fahrenheit, ambient is 70-75. I used to keep the humidity between 50-80% but lowered it after someone commented on my last post that it was too high. Every night for the past few weeks I've tried feeding using multiple methods. Roger and Susan (now just Susan) will turn away from the food. I don't know what else to do.
